Last fall i bought a 1986 Blue Water 19F Executive open bow boat. Has a 3.7L(470) 190HP Alpha 1.
Runs good, Starts easy but has the broken charge system and i now have the Alt conversion for it.
So this is more a fun project and nothing that needs done, Just a because i want to project. I Can collect all the parts up over the summer and next winter do the swap.
Question i have is this.
According to IBoat spec the boat weighs 2200# and is rated for 230HP max. I can not find a word about it otherwise on the internet.
Between a 96 or newer 4.3L or a 5.7(any year) What would you do? I have access to either engine for cheap enough and will have either rebuilt to marine spec.
I know with a newer 4.3L i will need to move to a Alpha 1 Gen 2 setup,exhaust and all the other little stuff. I think it will all work the existing keyhole?
I believe if i go with a older 350 i would need a new bell housing,flywheel,coupler and upper transmission along with the associated exhaust parts?.
I never pull skiers, once or twice a summer ill pull a tube.
Usually i like to cruise around 30/35MPH 3K RPM from my past experience with boats that seems to be close to the sweet spot but sometimes opening them up sure is fun when the wife is not with ya
Im personally leaning to the 350 but want opinions. Im not bleeding money but this is something i can afford if i start off going in the right direction to start with.
Thanks guys!
