    Default 10 tunnel hull cougar cub help

    I am looking to get some where around 50-55mph out of this boat... what would be the best power option ? it would need power trim and a 15" mid other then that light as possible.. 25hp is not cutting it

    I'm thinking your quest may not be realistic
    Since 1925, about 150 different racing outboards have been made.

    ............................................it seems to me ,that if that speed was attained, it would be a very DANGEROUS boat to drive.

    sounds like a job for a Stinger 75hp
    a hot rod yamaha 50hp may be best

    Im thinkin all answers correct even tho the results may vari. You havnt said enough about the rig.. motor, prop, setup & the thousand word picture. Id bet some things could be done with what you have within reason.

    Default cub

    the cougar cub was designed for the 15 hp motor,,,,25 max
    mercury had a program with the 15hp for a while with this hull in the 80s

    sides are short,narrow width,,sponsoms are short,,,compression made for 40mph max,average speed of 30-35,,different manufactures made this same hull in the 80s
    so working with that design
    gotta stay light on the transom,,,not to swamp it or give it transom weight
    to pull bow over at high speeds

    the tohatsu 40 with the sport c mods would get you close
    to the boats original design weight on transom
    also for more hp can use the omc 40-60 hp motors
    2 cyl and made in a 15" mid for john boats
    omc a bit heavier,,,,but more power to acieve speeds
    radicall direction is the omc 45ss motor
    shorter mid to get lower center of gravity,lots of power,,speedmaster for surface running,,,,,,,,,,,,
    but but trying these combinations,,,,,,,,,
    you will see the speeds your asking but the price is,,,,,,,,,,
    must be set up properly,,,driven in good wind,,water conditions
    wear safety gear and drive the boat with respect
    it will bite you if not

    ok well 50mph is not realistic.... my setup as is 25 merc 14p stock prop 5500rpms 25mph or so...I also have a ron hill cleaver 17p and it is slower with more rpms.... it should go faster then that right? the engine is mounted on the transom and the prop shaft is about 2" below the bottom of the boat, also I have tried a whale tail it helps on take off but hurts top speed by 3mph or so. any advise would help a ton.

    Default No Don't Jack It Up

    I'm serious here. This is the worst boat I ever turned over...With a 25 MP Mercury it will turn over driving straight...I suggest listening to John Miffco...

    Betty Cook started making these "BABY" Cougars....until she drove one...

    They should be saw up and burned....

    I think the sponson are too deep in the fron, if you are going more than aboutr 20, when you hit a wave they turn turtle....
