Re: 1987 Johnson 110 hp

you still may have some gunk in the carb did you use compressed air on the carb to blow out all passage ways

Re: 1987 Johnson 110 hp

Yes I did blew all the holes but come to think of it I did not adjust the float. do you think that might be the probl.

Switch to a known good portable tank and hose. See how it acts.

Re: 1987 Johnson 110 hp

Did that it still did the same thing one other thing is that when I got this motor the VRO was removed except for the fuel pump could that be a problem

Re: 1987 Johnson 110 hp

You're losing fuel, or spark.<br /><br />What happens after it dies? Does it immediately restart?

 

[mauiboy]

Re: 1987 Johnson 110 hp

yes it restart with no prob

Re: 1987 Johnson 110 hp

do you guys think it might be the float adjustment or could it be that vro pump?

Re: 1987 Johnson 110 hp

Have you checked for good spark yet like DJ suggested?

 

[mauiboy]

Re: 1987 Johnson 110 hp

Yes I have a strong spark on all plugs

Re: 1987 Johnson 110 hp

When it starts to die pump the primer bulb and see if it picks up. If it does check your fuel pump. Float misadjusted could cause this but I would check the others first.

Re: 1987 Johnson 110 hp

Thanks I will do that. is the vro fuel pump hard to clean or do I have to replace it?

Re: 1987 Johnson 110 hp

Is the cavitation plate above or below the bottom of the hull and by how much?

Re: 1987 Johnson 110 hp

Do you have a fishfinder transducer mounted on the transom, or even your speedo pickup could cause the roostertail.

 

[mauiboy]

Re: 1987 Johnson 110 hp

it is about 3" below.

 

[Solittle]

Re: 1987 Johnson 110 hp

For starters you need to raise the engine so that the cavitation plate is even with the bottom of the hull. When you get that done take it for a run and post back your rpms at WOT and let us know what prop you are running. You may need to raise it some more.<br /><br />Also tell us a bit about your boat and performance.
