I had my boat running peachy but my shift alignments where missed up. I couldn't shift before with-out killing the engine first... Now my shifting works flawless and aligned correctly!
The problem now, when i gun my engine all the way, i lose about 50% of power on my full throttle mode. I had my brother drive and i popped the top of the carb open to see whats up.....If hes going about 75% of throttle, the engine works fine. Once he gones it all the way the carbs valve opens up and the engine starts choking in a way... Either too much air the valve is letting in or too much gas as i see lots of gas spraying. While hes goneing it, i push force one of the valves back to its closing position and the engine runs fine again but it doesn't seem like the boat goes any faster, maybe 1 mile faster but operates a lot higher rpm.
The crab according to the dealer is "rebuilt by him" .. Its a quadrant 0-ester 7059288. I think that's correct serial. It has a manual choke which i had to setup the cable for although the boat does have electric wires for electric choke.
My question is, since i have a mercruiser 350 260hp engine, what is the best of the best carb fit for my engine... I have a 25 footer boat with cab and right now i do max about 30mph with 3 people and about 27mph with 5 people.
Before the cables issues.. it felt like my boat run a lot faster... We didn't have a speedo at that time though so i dunno how fast it really was but i know it felt a lot faster then now.... Also at that time i had a old prop set into a brand new outdrive with NO SPACING BUSHING WASHER! I had to buy a new prop because the old bushings don't fit new outboards. Now my grinding is gone and the prop runs fine it seens but the boat does vibrate a little bit when loaded going max.
What carb do i need and what can i do to make my boat run full speed. Or this quadrajet is fine just need some adjusting? Thanks ahead of time guys.
