    Default minimum power needed for a full size pump

    so if i have a 9ft boat that weighs about 500lbs full of gas what would the minimum HP and RPMs i would need to make a full size berk work on it?

    I am thinking of bolting a 1300cc 150hp jet ski motor to a full size berkly and stuffing it in my mini boat. Would this work? or are the two not very compatible with different rpm ranges and power curves?

    onthe same note what if i stuck a 4 cylinder eco tech in it instead?

    please dont put an ecotec in it! gettting power out of small motors is my thing lol. if you are going to put a car motor get something with a huge aftermarket support and knowledge, im not a Honda guy but they would be a great motor for a boat. or a some nissan. just my thought about the ecotec

    Im not sure what you are saying about the eco tech. It is a great motor with a huge following. People use them in all kinds of applications from rock crawlers, to dune buggies, to desert race cars. They have a big after market. make 260hp and run forever.

    anyway explain what you are talking about. I have never heard of anyone using a nissan motor. the turbo ford pinto motors are pretty popular and so are thw Subi motors. but a flat 4 is not going to fit in the mini boat. An inline 4 like the eco tech should slide right in with some new motor mounts

    are you talking about the Chevy cobalt engine? we might be talking about different ecotec engines, or i have my engine names wrong lol. i was thinking more to the tune of 300 or 400 hp turbo motor. in a mini that might be a little much but if it will have a big 4 cylinder then the option is there for more power.
    and i wasent trying to put down the cobalt motor, i was just thinking for cost, a b-series Honda or a 4 cylinder nissan would have a little more aftermarket support. just lookin out . any sport compact with a big following would be perfect, light weight, small size, high horsepower.
    i honestly wasent trying to offend anyone.
