Re-power project
Just bought a 1991 Bullet with twin 454s .. I plan to remove them, install a heavy duty bracket and power it with twin mercury 250 hp (or triplet) .. Any thought on wether the twin will be enough to take it to 50 MPH (max) or not?

Trees a couple 31 decathlon running twin 250's out there. Id think you'd see over 50 with twins. I don't think adding a third would be worth the added fuel usage to speed ratio.
Sounds like an Interesting project. Post pics if you can. Would like to see how it comes along.

VP of the tickfaw200
There was one on eBay with the back seat pushed back all the way to the back of the boat and Twins. Also on boat trader there is a Decathalon That's been 100% updated and has trips.

Why 250's? Have you got a pair lying around?
If you can go with bigger engines, a couple of 350 Verados or 300xs would seem a better option. Adding an extra engine doesn't increase speed proportionally to the expense and weight. Big twins will work almost as well as triples with much lower cost and a lot simpler installation.
I love outboards, great project, keep us updated.

The 250s are alot cheaper than the 300s and 350s .. Especially Older models like 2005-2010 .. It comes in two stroke also as I dont like 4-stroke due to its price and complexity .. The bracket is designed for 3 engines however I'm thinking that two engines are enough for a 10,000 lb 31 ft

Here's one already done with 300 e-tecs........
http://www.boattrader.com/listing/19...llet-102587957
Looks pretty smart and very practical but it's a lot of asking price for an old boat.
I love outboards but thinking a bit more about it, kinda not really Cigarette to put them on a Bullet. Hope you've got broad shoulders because you will likely upset some of the the Cig gallery!
