Can't get over 2k on water

Yes, tried that. Didn't make a difference.

That just confirms you have fuel pressure. Still could be a carb.

Going to check carbs. Going to verify stator, regulator, and trigger first. The carbs are a pain to get off, will save them for last. Lol.

sounds like fuel problem - you have checked your timing- had a problem once engine would not get up to speed and died- I replaced black fuel lines with plastic fuel lines- make sure they are safe with fuel- i noticed air in fuel line when running full throttle- make sure you have a driver this can be dangerous- it was not the fuel pump. Some kinda bug had made a coccoon in the gas fitting of the fuel tank. No idea what kinda animal can live in gas
Or you could put a see thru fuel filter and basically do the same thing. Not saying its a bug but one never knows next would be carb sychronization

Is the timing set right ?? Carb rebuilt with a good carb rebuild kit ?? The kits will give you the correct carb setting to start with. Will your spark plug leads jumpva 3/16" gap with a nice blue spark ?? Yellow spark means a weak spark. Just some things for you to check...

new fuel lines rated for outboard use. timing is set per manual. these carbs are not adjustable. tested spark and will jump 3/8" with nice blue spark. link and sync per manual also. keep em coming and i will keep checking. thanks

One thing you can try that's easy to do and might give you a clue. Get the boat on the water and make it do it then push in the key engaging the enrichner/choke. If the rpm jumps you know it's a lean carb issue

Will give it a shot as soon as weather allows. Too damn cold to do much right now. LOL.

Most likely stator or switchbox dropping under load..will show fine on a hose

 

[back2mylife]

Is there a test procedure for that? Can I do it at the lake still on trailer? In the 20's and 30's here, too big a pansy to run up and down the lake!

 

[Faztbullet]

You can test on trailer...just dont back it in too deep as need the prop to aerate a lil

 

[back2mylife]

It seems trigger was the issue. Replaced and took out yesterday and back to running fine again. I appreciate all the help. Unfortunately, now it is time to winterize...
Thanks again!
