MerCruiser 3.0 vs 4.3

And do low 60's at wot :-) I'm curious what my little 4.3L boat will do with the 23" prop. It's 50 mph (4 adults) with the 21" at 4600 rpm for a short duration ... only have about 25 hrs on the motor. Seems to have the power to maintain the revs ... I'll find out next season :-) |

MerCruiser 3.0 vs 4.3
Truly depends on how you are going to use the boat.
Do YOU ski, one or two ski's, kids tubing, fishing.... I had a 19 foot galaxy with a 3.0. I slalom ski and the boat could barely get me out of the water. I had to put a smaller pitch prop on it so that it could pull me out - that killed my top end. Flat out it would only go 35 mph. I bought a 19 foot Chaparral with a 4.3 this is a good all around boat. It can pull me up on one ski and still has a top end around 50. We can pull kids on tubes all day on a tank of gas. I would go for a 4.3 with fuel injection. They cost a little more but you get more HP and better gas mileage. Stay away from the 3.0 unless all you ever plan on doing is pulling kids on a tube and a little fishing. |
