What would a person have to do to modify a 27' pontoon boat to be able to use one motor instead of 2?

this 27' pontoon boat we have is able to handle two (2) 135 HP motors to a maximum of 270HP. But we'd like to change this so it uses only one motor. Is there some important issues that we should be aware of before we allow anyone to do the modifications? Thanks for your info|||no there would be no problems doing that, sounds like a good idea, thats a lot of h.p. ,, you can mount the motor in the middle, making sure the cavitation plate is just under the surface or you can just leave it where it is and correct the thrust with the steering wheel|||Fist off if you make it a single engine centered it will have a long turning Radius%26gt; And be very hard to maneuver%26gt;And you will have to increase the HP on a single unless you only want to go slow and not have a crusing speed%26gt;A third pontoon will need to be installed for the support of the weight and torque%26gt; I have see a small engine mounted on the from to help make turns but it was under water most of the time%26gt; The length is your real problem for a single engine I had a 24 with a single and it worked Ok but sharp turns were an issue%26gt;|||OK, so my guess is there are little transoms mounted at the end of each pontoon. To go to a single engine you will want a single transon in the middle of the 'toons.





Gonna need a pro aluminum welder to fabricate a new transom and motor box to be mounted in the middle, with all the reinforcing to hold a large engine.





Linkage cables will have to be pulled and replaced to allow for the single engine.





Steering cable will have to be altered and most likely shortened to come to the new single engine and location. If the steering is hydraulic this will have to be altered and moved.





The new transom will be the key to the project. Best of luck.





Edit: don't sweat the length with a single, I have driven many large pontoons with singles and it wasn't an issue.
