dual outboards

[Cut n' Jump]

I have a 15 1/2 foot trihull that seems very heavy. Current engine is a 70 hp evinrude that runs fine. I had a complete spare johnson 70 that I overhauled last winter. Would it be feasible to mount both on the back of my 85hp max rated hull? If so where could I find a cheap bracket or would I have to make one?<br /><br />ps would one motor have to turn backwards to prevent roll?

It would be a bad idea, C&J.

Re: dual outboards

twin 70's would be 140hp, and your max is , um, let me do the math... oh, 85, sure youre in the clear, send pics

Wait a minute. I have never owned, or had twin motors on the back of any of my boats, but the question is: <br />If you have say 2 50hp mercs, do you get 100hp out of them or do you only get 50hp and spend more money on gas? I realize that they push the boat up on plane quicker, but really is the point of having 2 o/b's. Wouldn't it be better in this situation to have a 100hp instead of 2 50hp motors? Just wondering.

I've chickened out on this idea a couple times now. I already own two motors and don't own a 140 hp motor. Let's say I get another boat that handles 140hp. Then would it be a good idea?

Good combo for the right boat. I got a couple of 110s on a 23' CC.

I say do it, you only live once. Aslong as its not a problem to have two engines rotating in the same direction.

Guys, 2 70's doesn't make a 140. It makes 70 that neither of them have to work as hard. I doubt that you would be able to up the pitch a whole lot to make it much faster than it is now, you would just be able to get from 0 - top speed a little faster, and unfortunately, use almost twice the amount of fuel. I've seen boats that are rated for a single 250hp or twin 200's or 175's. I think it's more of a weight issue than over powering the boat.<br /><br />Just my 2 cents.<br /><br />Craig
