Place for High Performance upgrades?

[Tommy McDermott]

i have been looking for a place that sell high performance parts for our boat and cant find anything :( does anyone know a good site to look for?
4.3l mercuiser with 190 hp
alpha I drive

[Rootsy]

exactly parts are you looking for?

[Tommy McDermott]

intake manifold, 4 barrel carb, headers, maybee thru-hull exhaust

[Rootsy]

cheapest route and easiest place to find the intake and carb would probably be summit racing or jegs... make sure you get a marine certified carburator though, they do sell them. can't help you on the exhaust since i have no idea what boat you have what manifolds or engine etc etc etc

1990 baja 19' 190 dsr with a mercurser 4.3l.

I have a 4.3 and ordered the edelbrock intake and 4 barrel from summit racing it madea huge difference i gained 400 rpm now i need a bigger prop.

Part numbers

intake edelbrock 2111
carb edelbrock 1409
calibration kit 1485

you will also need a throttle cable bracket from a 4barrel 4.3 there are two diffrent ones that mercrusier makes be sure and get the one with two sets of bolt holes for the carb flange.

I would highly recomed this upgrade. my next upgrade this fall will be a cam and ported and poished heads. should hit 275-300 hp

I cant wait

porting and polishing gives a ton. thanks everyone, i will look through jegs one more time.

I can have the port work done you would need also plan on a ignition upgrade Merc s are famious for burning only 75 percent of their fuel.
