brandenjg Posted March 24, 2016 Author Share Posted March 24, 2016 Thanks Strowager. I already have punches so just the gasket material to get. I'm going to bike to halfords and wilco to see if they have a suitable material. Saves me waiting for delivery from ebay. Damn bank holidays.

brandenjg Posted March 28, 2016 Author Share Posted March 28, 2016 Beginners mistake. The outboards all back together but didn't line up the water pump ( the 2 pipes didn't slot into each other when replacing the lower unit) so have to take the outboard off again to quickly line it up then should be sorted 2 Quote Link to comment Share on other sites More sharing options...
brandenjg Posted April 14, 2016 Author Share Posted April 14, 2016 Quick question. What does this do and am I right to of adjusted it to sit on top of the plunger? Had the carb apart to clean it as had another issue with the outboard and noticed it looks different to other pics of the same model. thanks again again Branden Quote Link to comment Share on other sites More sharing options...
BroadAmbition Posted April 14, 2016 Share Posted April 14, 2016 Blimey that takes me back a looooong time to a bygone age of points/condensors and the like, if I am looking at what I think I'm looking at, that is a method of advancing the timing by a vacuum, could be wrong though as a photo showing a larger area would help, I would tentatively suggest that yes it should sit on top of the plunger other wise when the shaft is moved by the vacuum housing it will have nowt to push against etc Hope this helps Griff 1 Quote Link to comment Share on other sites More sharing options...
FairTmiddlin Posted April 14, 2016 Share Posted April 14, 2016 Looks like a fuel pump for acceleration When you open the throttle the left arm rotates and pushes the plunger with the spring on it down This injects a small amount of fuel into the carb to give it a quick boost Quote Link to comment Share on other sites More sharing options...
BroadAmbition Posted April 15, 2016 Share Posted April 15, 2016 I think FT is right there if the photo is part of the carb Griff Quote Link to comment Share on other sites More sharing options...
Wildfuzz Posted April 15, 2016 Share Posted April 15, 2016 brandenjg get yourself some de greaser on it to..... must be my OCD for mechanical cleanliness coming through. 2 Quote Link to comment Share on other sites More sharing options...
FairTmiddlin Posted April 15, 2016 Share Posted April 15, 2016 Stuart These parts are greased for a reason, as they rub against each other degreasing causes wear! If you don't reapply grease afterwards 1 Quote Link to comment Share on other sites More sharing options...

If you don't reapply grease afterwards I agree, a greasy outboard is a happy outboard The lever also opens the butterfly on the engine side of the carb. heres a pic of the entire carb and the butterfly opened and closed. 1 Quote Link to comment Share on other sites More sharing options...
brandenjg Posted April 18, 2016 Author Share Posted April 18, 2016 I fix one thing and another thing plays up. Everything is now working but I can only go 3-4mph at full throttle I'm losing hope of getting the outboard sorted. Got a few things to check and if they don't work It doesn't look like I'll be cruising anytime soon as can't afford repairs at the moment. Oh the joys of boating on a budget .

Oddfellow Posted April 19, 2016 Share Posted April 19, 2016 The accelerator pump should not generally be in contact with the plunger unless it is in operation. Making it contact will over-fuel the cylinders too early which can cause the engine to hiccup when opening the throttle. Make sure you use a water-proof grease on all engine parts. Does it feel like it's struggling at full throttle? Does it rev all the way? Does it pick up properly when you open the throttle quickly?

brandenjg Posted April 19, 2016 Author Share Posted April 19, 2016 There's a small gap so the plunger isn't pressed unless I accelerate. The outboard sits perfectly in neutral, goes into gear and pulls out of the mooring at the normal pace and rpm. As I leave the mooring and accelerate the outboard accelerates smoothly and rpm rises as normal but at full throttle it still sounds sweet but doesn't have any go? No hiccups and no cutting out. Full throttle has the sound and power of 1/3 throttle. Branden. Quote Link to comment Share on other sites More sharing options...
grendel Posted April 19, 2016 Share Posted April 19, 2016 you said above the lever also operates the butterfly, is the butterfly opening fully at full throttle? Quote Link to comment Share on other sites More sharing options...
brandenjg Posted April 19, 2016 Author Share Posted April 19, 2016 Hi Grendel, yes it fully opens as the lever is pressed down by the throttle. Quote Link to comment Share on other sites More sharing options...
brandenjg Posted April 19, 2016 Author Share Posted April 19, 2016 Just thought, could a new inline fuel filter be the issue? The old one was small and the pipe layed flat inside the cowling whereas the new one from the service kit is about 4 times the size and now sits above the fuel in and is held in place loosely by cable ties. I may be restricting the fuel by having the filter high up and may have a pinch point in the fuel line. could this cause half power? Quote Link to comment Share on other sites More sharing options...
grendel Posted April 19, 2016 Share Posted April 19, 2016 first check that its not full of air, then check for restrictions in the fuel line. Quote Link to comment Share on other sites More sharing options...
Oddfellow Posted April 20, 2016 Share Posted April 20, 2016 Propeller bush is probably shot. Shaft spins, but the prop is sent around by inertia rather than full mechanical contact. Quote Link to comment Share on other sites More sharing options...
brandenjg Posted April 20, 2016 Author Share Posted April 20, 2016 That's one of the things on my list to check when I next go down. Will be annoyed if it is, as I've only done roughly 10 hours on the new prop although I did fit it last year but haven't had a chance to use it very much. If it is at least it's an easy fix. Thanks for the advice, I'll update once I've been back down the boat. Branden Quote Link to comment Share on other sites More sharing options...
Oddfellow Posted April 20, 2016 Share Posted April 20, 2016 Well, if you're getting full revs, no obvious weird noises and the like, the only reason you're not getting speed must be to do with drive. The gearbox drive dogs either engage or don't and there's no clutch to slip. The thinking must move to the likelihood that the propeller isn't turning fast enough. Or, perhaps you've snagged a WWII mine? Quote Link to comment Share on other sites More sharing options...
