in twin inboard applications(propshaft thru the bottom of the boat, not sterndrive), one engine turns opposite the other so, counter acting props can be used to tame torque steer. This is ususlly done by swapping hte timing chain set for a gear to gear, it allows the cam to spin the same direction, but the crank spins oposite normal direction. requires a special cam as well. If you are planning to repower your boat, I'd look at soemthing a little more mordern like a chevy power plant, easier to get parts for it. 4.3 V6 would be a nice size

no he anit on drugs! very common used with twin motors eliminates torque steering just like a tank on tracks you really could steer the boat by using the motors. go starboard or port. mate the best thing you could do is stick with your motor and fix each problem at a time. you got enough steam with that motor. if what to go faster then buy a go fast boat.

do a compresion test on your 4 cylinder, if its fair, pull the head, have it gone thru and freshend. Have the machine shop install the rocker arm up grades. try compition cams magnum rockers, they are cheaper than full roller and far better than what you have, you may have to install big block chevy rockers and studs. DO a search for cheap 460 ford rockers, a whole bunch of different ideas came up. Put it all back together with the stock 2bbl set up and try it out. At teh very least, you will have a good motor to sel if you want more power. My old roomate had a 17 Stingray owrider. I did a few minor mods to the 3.7 2bbl motor he had. Teh boat would run 55 mph with alight load. We used to pull two wake boards all teh time with four peopl in the boat. Don't give uyp on that four cylinder, its a good powerful motor. Easier to fix what you have than start a new

well thamnls spares just dont want to go the wrong way about it
i have to options buy that 302 windsor of ebay and hope it fits without too much trouble and rebuild it first the next one is buy a edelbrock preformer head with the larger chambers fit the rollers and head comes complete with studs and rollers i was going to go for a 1.8 rocker arm and mod the manifold for a 600 cfm vac look may even pull the engine down and rering ti and get the cam ground to a mild solid but will it all be worth it in the end i dont mind if i have to spend money in the end it will be a better boat it working out which way to go Last edited by aussie; 03-14-2011 at 08:05 PM.

larger head chamber makes for lower compression ratio without the proper pistons. look just get a nos kit. you want power . power you will have doubled. but if abused you wont have any motor left.
