I just bought a boat 4 weeks ago, and took it out few days back, and it wasn't pleasant .. First it didn't want to start, finally started but it had very low idle, and when I pushed in gear died off. I took it home, got new sparks .. NGK.. same thing.
I tried to move around the spark plug cable, and voila started idling better!
So I started unplug the top cylinder spark plug to check if the cylinder works, and after i pulled it , rpm dropped, so the 1st ok!. The second plug was pulled and no change in the idle , so 2nd cylinder won't work. Lower cylinder works , so 2 of 3 is good. I swapped around the cables and ignition coils ( I hope they are same) , and I got a same result. 1,3 good. 2 won't fire.
According to the previous owner, and the invoice I got from him, about 4 months ago he had a same issue, and a shop replaced the CDI unit ( charged him $600) and new carburetor kits, new gas, bulb, etc.. So he paid $1800... The motor started on his driveway when I bought it, but I have this issue now.. Again.. I checked a label on the CDI, and it shows 2009! The motor is 2007, so either they ordered an old part was sitting in a warehouse somewhere or they screwed him over ( and me ) with a used CDI..
I can't bring it back there ,( I won't trust them..) and I was wondering if you guys would have any idea what can be wrong . I will take it to a mechanic this weekend, but I was wondering if any of you was facing with similar problem..
I also downloaded a wrong service manual by accident, I have a pdf format for Worldwide: F40BMHD, F40BWHD, F40BED, F40BET and Usa, Canada:F40MH, F40ER, F40TR, if someone has by the chance the F40MLH Service manual: LIT-18616-02-16 I would willing to trade mine
My boat doesn't have a tachometer , and I would like to install one, and i was hoping if i will found out info about that in the manual , also looking for a procedure to "link and sync the carburetors".
Please help me out .
Thank You!
