I have an older model 18' baja bowrider. It is powered by a mercruiser 470. I would like to pull this and intall a small block ford v8. Probably a 302. I believe the inline 4 is a ford engine but don't know if it will bolt up or not. Anyone ever tried this. The boat runs about 44 mph and will pull tubers and skiers as long as the skier is not too big a guy.(this means I don't get to ski). The 470 engine is 170 hp as it sits. I would like to get to around 225 or 250. The drive is a mercruiser "R" drive or I think it is also called a #1 drive. I have heard they are good for this horsepower with no problems. HELP!!. I believe if this works I will get a lot more torque out of the hole and pick up 10 or 15 mph.
