  • 2000 proline 2700 with twin 350hp yamaha outboards!!

    to do or not to do,
    I have a proline 1999 2700 model,,with stainless marine dual engine bracket.
    it had twin yamaha 300 hp on it,(dual engine bracket has a plate attached to it so that the engines sit wider out,it moves each engine out an inch each corner).
    now I want to repower with 2 yamaha 350 hp outboards I have.
    yesterday I installed them on the boat,,and it seems that transom and bracket have no problem with weight issues etc.
    I have the dual con*****er command link setup,with cables,gauges, hubs,keyswitches etc, also the software to hook everything up. this i will do tomorrow.
    now,,,,,my key question I have for you ,,is this a wise move,,or should I totally forget about this setup,,remove 1 engine, and buy a single command link con*****er? would this proline 2700 1999 be able to hold this weight ?
    it is not about the totall max power I have,,the boat is rated max 500 hp,,and now it is 700hp.I will never throtlle the boat wide open,,I just want the accelaration for quick plane,,,and rest will be *****ing for fishing purposes.
    my utmost important question is,,what is your opinion of this setup about proline 2700/stainless marine twin outboard bracket(reinforced to the side steps),and the twin 350"S????
    really to get replies ,,as tomorrow I start with installation cables, shifter etc
    regards

    like you said 700 is 200 over the rating on the boat. Even if you do not plan on running it WOT, when you open it up out of the hole you putting the strain on the boat. And then it depends on how you prop it also
    Your Insurance company probably won't like it and I am not sure about any other regulating body where you are located.
