Re-powering a twin engine houseboat with outboards
by Crab Trap
Plenty of twin outboard installations on houseboats
I'm considering purchasing a houseboat and re-powering with twin outboards. Does anyone have any insight, experience, or advice on this?
I have my eye on a 1986 twin inboard 43' Standard Gibson and am thinking of installing an engine bracket and powering with twin 60 hp high thrust Yamaha's. Some questions:
Will I be able to find control cables long enough to reach the flying bridge?
Will I be able to attain cruising speeds of 5-7 kts?
What kind of fuel consumption am I looking at?
Thanks for any help, Crab Trap.

Crab Trap, thanks for posting in the houseboat forums.
Now in regards to repowering with twin outboards, YES, it is very doable. You may first want to do a cost analysis on the anticipated step, VERSUS rebuilding what you currently have.
Now you didn't mention what you intended to do with the houseboat. Do you want to stay in your local area and go out occasionally, or do you intend to do some long distance traveling?
Once you do a cost analysis, and understand what you want to do with the boat, you'll will likely clearly see which direction you should take.
From what I understand and have seen, you should be able to get control cables to reach the flybridge.
Now to attain a 5-7 kt cruising speed, the twin high-thrust Yamaha's should be able to do that, and still give you good fuel consumption numbers.
I don't have exact fuel consumption numbers, but I will provide a guesstimate of @ 2-2.5 mpg while running at @ 5 kts (a good hull displacement speed).Lastly
