boat is a Crowther buccaneer trimaran
. it is 10m long and weighs about 3300 lbs. design weight loaded is 5000 lbs. When I bought the boat it had a high thrust 8 hp honda
four with alternator electric
controls, etc. This is a rather heavy engine
(~130lbs.) and was mounted on a stern extension made of heavy timber faired into the shape of the hulls adding 2 feet to the boat with an outboard
bracket on the rear. With this setup the boat squatted in the rear and cavitated horribly in any chop. The waterline was way high on the stern and the bow was out of the water
with this arrangement. This boat has rather fine ends and the mantra of keep the ends light is in constant refrain from all who know this design. I cut the transom extension off, dropping ~100 lbs from the stern of the boat.
I am now ready to mount power elsewhere, most likely a bracket on the aka (crossbeam). I saw another trimaran
online with two engines mounted on either side and thought this could be a better arrangement. The 6 horse engines weigh 55 lbs each and would give the improved maneuverability of twin engines.
I need to get an engine
for my dinghy
, and think that one of the 6 hp engines would be perfect for my 10 ft porta-bote. I could use one engine on the dink when at anchor
and have both for the tri when at sea, etc. This should give me 12 hp instead of the eight I have now, and be about 20 lbs lighter overall. I would give up the high thrust of the 8, but would have two props in the water
when needed and be able to just run 1 for economies sake. Should the thrust of the pair be too little, I could change to props with less pitch
I am about to splash $2700 for a pair of tohatsu's Any one want to chime in on whether this is the perfect solution, or not?
