    Everything done but low rpm at WOT. Distributor spring?

    Scott mentioned that way back in posts but there was some debate that I should still get enough air and fuel. I was getting no vacuum at wot so that seemed to indicate to some that I was ok at current cfm.

    Everything done but low rpm at WOT. Distributor spring?

    Plugs were just put in about 50 hrs ago but I can't check them again because I have to remove manifolds to remove plugs. I just replaced the manifolds for $6000 so I would not like to do that again. Rpms were same as before new plugs. Plugs at that time were coffee mostly. Not bad.

    Everything done but low rpm at WOT. Distributor spring?

    Nice pic with all those 80s boats. Indian Arm is where we go often. You might remember twin island from the attached pic. Anyways, I like your idea for dropping the weight. I did check the secondaries ( I was driving with friend looking - perhaps friend got it wrong) but should re-check. Do you...

    Everything done but low rpm at WOT. Distributor spring?

    Thanks, I see you are in Edmonton?, Of course I am trying to solve the WOT issue without removing the engine from the boat, especially since I just did all the upper end work. I know the valve guides and seals are brand new. I suppose I can just be happy to run at 8 knots at 1800 rpm and still...

    I am in Vancouver BC boating in the ocean. No ideas on hrs, but only 50 since head rebuild. Engine does run very smooth. Could not plane when I got it. Compression was good then but still changed the heads as mechanic said we could check pistons and eliminate valve as an issue, and reduce oil...

    Everything done but low rpm at WOT. Distributor spring?

    Thanks, I am going through everything again. I rechecked the throttle linkage and noticed that the carb throttle arm was getting held back a bit by a tab on the intake manifold. I thought I had solved the issue. It did get me another maybe 400 rpm at WOT (now about 3500) but still not enough...

    Everything done but low rpm at WOT. Distributor spring?

    Yes, I had the exhaust manifolds and risers/elbows off and was able to inspect inside the y pipe.

    Everything done but low rpm at WOT. Distributor spring?

    Thanks. Yes, exhaust is clear (just had exhaust manifolds off) and can easily get full revs in neutral.

    Jimmbo, that is Bnewton530 who said that (not me the original poster with this issue). Does not matter if I "mash" it or go gradual - no plane. I just bought a 4 blade prop online that has 2 inches less pitch. Will try that and report.

    Everything done but low rpm at WOT. Distributor spring?

    Do you mean just push handle forward fast instead of gradually? I don't have any more travel left with my throttle handle all the way forward. I also removed throttle cable to see if the carb valve was being restricted by the cable.

    Everything done but low rpm at WOT. Distributor spring?

    Not a dumb question. I did not weight it but it is a pretty heavy boat to start with. It is almost 30 ft with command bridge and wide beam. Hull/deck are in pretty good condition - I don't think it is water saturated. The factory weight of the boat is about 7000 lbs. dry and unloaded.

    Everything done but low rpm at WOT. Distributor spring?

    It was there when I got it. Had it rebuilt. Did not consider that it was not original.

    Everything done but low rpm at WOT. Distributor spring?

    I have had it for 2 summers and it has never achieved a plane. Had compression checked at 150 all cylinders. Since then, top end redone with new heads, plugs, wires, distributor. Rings/pistons were apparently ok. Timing chain and sprockets, camshaft were not changed. vacuum 14 at idle

    Everything done but low rpm at WOT. Distributor spring?

    sure, but I have checked everything in the list: 1. Fuel condition. Type and Octane possibly old fuel - 2. Propeller pitch or diameter, damaged blades 3. Restricted fuel pickup tube or anti siphon valve Fuel System Test 4. Crankcase oil volume, high oil level can cause aerated oil and lifter...
