outboard powered 40 footer?

Re: Surely ?

All that weight at the extreme end of the vessel can do nothing for the balance of the vessel and quite probably its sea keeping handling.
Good reason that engines are usually located as low and near CoG as possible. ?
You would need to haul the boat every single time for any serious servicing and am going to guess that service intervals on those babies are lot closer together than for any inboard diesel.

Re the servicing, I highlighted the Evinrude G2's for exactly the opposite reason....they don't need servicing for the first 5 years or 500 hours! And how about the sterndrives, don't those need servicing (in theory) out of the water every year?

The original premise of this thread was to suggest outboards on boats up to 40ft mainly for the reliability, low service costs (and I was thinking about the G2's), less time out of water (if any) and lower hassle/stress! Reading about Nick Burnham's costs in just his first year for his single diesel/sterndrive set up reminded me of how stress and cost free my little boat has been since i bought it 2 years ago with a 75hp 2-stoke outboard that has been 100% reliable over that time.

Understand your point on the weight. D4 300 diesels and sterndrives weight about 650kg each side so 1300kg in total low down. But still at the back of the boat. The G2's weight 244kg each so 500kg in total hanging right off the back. 800kg+ difference. With that weight and position difference maybe the COG wouldn't be quite so different. But anyway the hull would need to be purpose designed for outboards I would think.

Also the water tank, holding tank and fuel tanks could be moved forward and to the middle of the boat where the inboards wold have been to offset the weight shift.. Assuming the space isn't reclaimed for more internal accommodation..
 
Re: Surely ?

"Stress and cost free " ( or at least much lower servicing costs ) - yep that is why i have finished with diesel and stern drives and am considering the petrol outboard route. And,speaking from experience, the less eletrickery the better !!
 
Re: Surely ?

great find! American layout and no hard top but definitely the engine principle I'm thinking of. Outboards further apart so there's a walkway between them out to a bathing platform and maybe provides better low speed manoeuvrability. Sun pads/seats on top of outboard covers. big cockpit, plenty of space for tanks, etc and generator. low draft, engines tilt fully out, big aft cabin. 38knts WOT and 27 best cruise at just over 1mpg with 247 mile range.

here's an actual test of it:

Isn't one of the major plus points of an outboard that it puts the weight right at the very rear of the boat?

Not a hard top but it looks the dogs do do's.
