Hi A Axium propeller gives a higher efficiency along with less weed pick up i have one on my present boat very pleased with it. It does cost a little more. John

Hi Green flag breakdown service was the go to for people in the trade as there garages would put their customers first in the que before the aa rac and others, i was with them for years until two years ago when they where bought out by a insurance company the prices went through the roof i dont have any info as regards there call outs. i now use another provider. as with any insurance i would rather pay and never make a claim. John

Variable pitch props require a hollow prop shafts for control rod or oil gallery's to activate/control them, cost would be one thing and a prop-shaft of 1" to 2" dia would be impractical. John

Hi Batteries do not require topping up checking once a week , twice a year is ample ,i check mine once a year at end of season,and leave on the boat connected, i also have a solar panel to maintain voltage so i dont need to remove or connect batteries to mains trickle/maintainer charging, yards may remove all the batteries to a battery shop which would be easier to check and trickle charge over winter,then at end of winter they would disconnect from buss bar and then let them stand for 24/48hrs then check specific gravity and voltage to ascertain battery's performance before replacing on the boat, perhaps Vaughan could give us best practice that yards might/do follow. lead acid batteries may not last as long as AGM but at half the cost they only have to last over half as long together with the scrap price being higher when life span is finished to be more cost efficient for the business. John

The only problem with shore power is when the hires drives of without unplugging and causes damage as has happened twice at Horning this year already. Hire boats need a tug release connector if they are to have shore power cable provided. John

Hi That's why yards use lead acid as they are the most cost effective, they do need a certain amount of maintance ie topping up the with distilled water but with engineers on site , Advanced regulators can be fitted to any boat at little cost, they only require wiring alterations and will halve the the engine running time to recharge the battery's saving fuel, wear and pollution. John

Hi RS there are moorings ether side of the bridge if you have to wait for clearance along with a pub called the Bell. John

Hi If yards fitted larger alternators or two alternators along with a advanced regulator this would alleviate many of he problems, also battery's dont like being left not fully charged when standing for any length of time. John

Hi Bogart Steel rusts little under water it is stronger than fibreglass will resist collisions easier to screw to but will rust if paint is chipped of,will touching up if chipped is colder and noisier unless insulated, steel is cheaper to build but is more difficult to have roundy corners, steel doesn't need to be lifted out each year unlike fibreglass does to prevent osmosis, can be repainted easily, but not as easerly shaped as fibreglass is so often not as attractive, but steel boats often last longer. swings and roundabouts,for and against. BUT if second hand immaculate boat is cheaper in the long run unless you are skilled and have premises to rebuild a boat along with lots of time. John

Hi Smoggy That means it has cost more than the pump price.John Mouldy higher cetain means better starting and less knock and less carbon build up and cleaner injectors. At the end of the day your engine you ay the bills. John

Hipperson's Diesel price for GTL which has a higher Cetain rating and longer shelf life is £1=68 Lt for 60/40 split. toilet pump outs are 1= outlet £18=00 2= £23=00 and 3= £28=00 as of 2/4/22. John

Hi The large nut on top of the top hose mounting would be for venting the engine, remove header tank cap first, and if you clamp the thin hose from bottom of header tank you can remove/unscrew the large nut without losing coolant and check that it has a small hole about a third of the way down the treads and it should have a copper washer under the head of the bolt/plug then replace plug finger tight release clamp on small hose unscrew plug until coolant runs out then retighten plug.do not over tighten make sure header tank is kept half full while venting. John

You should be able to vent the very top of the tank to remove air to reduce Legendar. The pressure relief valve can be fittd any where BUT is usely at the very top so that it can be used to vent tank of air. vertical tanks work best but not always easy to fit a large enough one hence parrilla ones. i would guess that the blue pipe with the nonreturn vale hose goes to the fresh water pump this should go to lowest tank connection. John

Ray water will only come out if coolant is under pressure with cap on and engine hot (not recommended) or if header tank cap is removed and as it is higher then engine you dont need to run it. John

Hi Do you know which of your hoses that go to the calorifier comes from water pump this should go to the bottom connection difficult to see this from you picture it looks like it is on the side ref turn tank 90*??. what do all the hoses do/go to. John

Hi Ray Looking at your tank is it held by two straps or does it have a fixed base? what i am thinking is the tank needs rotating 90*, your engine is a base Kubota Nanni is a French firm that Marinizes them, on my Kubota the heater pipe comes from the rear of cylinder head. suggest a trip to Peachments at Brundle they are the local agents. i have tried to google the cooling system but unable to access a picture, except for one that shows there are two outlets on top of head near thermostat housing. the engine should run with a 85 degree thermostat does your engine get to this temp? John

Hi Ray Normally the hose to the top of calorifier comes from the rear of cylinder head as Smoggy says has it been like this before and did you have hot water. The engine looks new. you will get water from both as they are below level of header tank, both hoses getting warm equally is not right, is there a connection blanked off at rear of cylinder head. do you have a user hand book for the engine? what engine is it! can you feel the hoses closer to the calorifiera e the top one should get warmer first if you take both hoses of can you see the impellor of the pump in one of them the return hose from the calorifier should go there ie return from tank. if you would like to phone me while at boat seed me a email and i will phone you. A picture from directly above hose connections would help John

Hi Ray a picture might help, but if you cant reach the 1/2 inch hoses that come from the engine you will have may be remove every thing flush through with hose and start again the calorifier will have 4 hose connections 2 to engine coolant and a inlet from pump and outlet to taps, the red capped valve at the top is a pressure release valve which may have a hose connected to it to drain/divert any water that gets released by the valve over board or bilge. John

The thread will be unf if fine or unc if coarse. John

Hi Ray Remove the header tank cap then undo the top hose of the two that come from the engine with engine running at a fast tick over gently full top hose of off the calorifer coolest from the engine should run out if only air hold until coolant runs out then push hose back on and refasten, header tank my want topping up with a 50/50 mixture of antifreeze aftr wards, then as engine gets hot so should the hose at the calorifera, if no flow engine will need flushing or hose may have collapsed internally,or coil in calorifira may be blocked, have you checked the temp of hose from engine as i last suggested to you?. the water will only get as hot as the engine provided the engine coolant is able too flow through coil in the calofirera and back to engine at its worse the engine coolant pump may be worn on the vans and need replacing if no flow. John

Hi So every body with a gas and electric meter will pay £267=00 odd per year regardless to how much power they use, if suppliers only get £30=00 =£60=00 where does the other £207=00 go to? do the electric posts have to charge a percentage of this , not sure how you would calculate it. John

Hi The price cap of 28.34Kwh and 45.34ppd is the max they can charge for electric and gas at 7.37Kwh and 27.22ppd they the utility companies can charge less if they wish This is the information from Ofwat that i obtained . John

Hi Correction that is gas should have been 14.47 p kwh 5.0ppd for electric. as so still a big jump too look forward to in April to 20.87kwh. John

Hi That would be last years rate i have been paying 3.3p per kwh plus daily rate i received yesterday from my provider that it would be going up to 20.8p kwh plus 24.04 p p day in April surjest you get as many as you can before they re calibrate them to the April rat when the price can be as much as ofcom max rate of 28,34 kwh plus day rate of 45.34 ppd so likely be more than 30.0p kwh if they charge the maximum. John

Hi have you checked where its made. Crew saver tend to be the choice of Police, Harbor Authertys, life boats etc
