  1. Hello and welcome, as you have seen, I am quite new here also. It's very good to keep up to date with local knowledge. Paul
  2. . Hi, After my recent experience I would not go past Blackfriars Bridge. High tide may be safer, Bishop Bridge is the lowest. Paul
  3. Hello Hockham Admiral, If you go along the Wensum through Norwich, as you get closer to New Mills Yard, the river gets shallow and is full of debris, such as shopping trollys etc. In this location at Easter I wrecked a new prop. and then aquired two woolen jumpers round the prop. Thankfully I could lift the sterndrive to clear the prop. Paul
  4. I'm sure this weed cutter must be in very good condition, because of the very few times it must be used !! I wish they would use it more on the Yare and Wensum near Norwich. Paul
  5. Hello, It's very interesting to hear all your views re. petrol verses diesel. I chose diesel because I believed it to be better than petrol for low speed river use. I went down the route of marinising a vehicle engine purely on the basis of cost, but it was a lot of work for me over the winter. The fuel consumption I find quite amazing, but I am running just above tickover. I think the fuel useage will change drasticly when I try to plane the hull ! For this year at least, I expect 90% of my use to be on the river.
  6. The gear ratio I have is 1.61:1, which was suggested to me as ideal for the diesel, the V8's were not a high reving engine. I did use this ratio in the prop calculation, plus I bumped up the weight of boat ( to allow for the beer on board ) I have not checked the max off load revs. I will do it this weekend. The engine was re-built, injection pump serviced and calibrated etc. before installation. At 1100 RPM, 6-7 MPH, I'm using just over 1 litre per hour, that is quite amazing compared to the V8. Paul
  7. Thanks for the link, I have just done the calculation, with the resulting prop size 15.75" X 11.75" I have a 15.50 X 15 at present on the boat so it does explain the low revs and therefor lower power output, particularly from a turbo / intercooled diesel. The suggested max speed is 20.50 MPH, I will be happy with that. Paul
  8. Hi Antares, My boat is the model before the 2556. It's the 2450 Command Bridge, 8' beam with the Volvo engine and drive. My V8 was totally worn out, it would only achieve 1500 RPM with compression readings from 30 - 45 psi ! It seemed more sensible, as I had to change the engine, to go to diesel. The guys in the States say if I change to the duo-prop drive it will make a big difference. Paul
  9. I'm not sure how the speed is yet, it's great on the river at displacement speed. I had to guess at prop size, but I got it wrong and can only get 2400 RPM, when the engine should rev. to 3600. I am hoping the boat will just plane when everything is sorted.
  10. Hello, You may have seen my post as a new member last night. Do any of you have views regarding changing from a petrol engine to diesel ? I caused many members of the Bayliner site in USA to question my descision last winter to remove the 5 litre V8 petrol engine and replace it with an Isuzu 2.8 turbo diesel. I am very pleased now, runnung costs are almost nothing when compared to the thirsty V8. Regards, Paul
  11. Thanks Antares 9, I found the site some time ago, but only just got round to registering. It will be good to be part of a LOCAL boating community, compared to my posts in the Bayliner Owners Club, USA Paul
  12. I have just registered as a new member, not new to boating, started over 35 years ago, but have not used the Broads for some ten years until buying another boat recently. Regards, Paul
