Ok so I am out of ideas on this one. I have a 98 speedster, the twin with 220 hp. I have had all kinds of problems with this boat and now I have a new one I cant figure out.
On my RH engine, the Aft cylinder is dead. I can pull the spark plug lead off of it and it will keep running, if I pull the plug of the fwd cylinder it dies right away. I am getting spark and have good compression.
I ended up changing the engine last summer after a bearing in the crank went bad and busted through the lower case. This season I put a new carb on the aft (PTO) cylinder since my old one had a broken screw (I am trying to sell the boat and didn't want the new owner to have any surprises such as the temp weld job holding the needle valve retainer down. Hey it worked all last season). So it has a new carb and the jetting is the same. When I took it out for the first time the season it ran fine for the first 10 minutes then I lost power in that engine. I am unsure if it went into safety mode or was just running on one cylinder.
Anyways, I am thinking it is kind of unlikely that it is the engine or the carb but who knows at this point.
Has anyone ever heard of a fuel pump being weak and only pumping enough gas to the fwd carb and not getting any to the 2nd one?
