You can if you ask the right people

I've got a 4.7m Zodiac with a 2 stroke mariner 50 which weighs 75kg IIRC, with 2 people it's hard work to lift on and off, if it didn't live on a trailer it'd never get used.

Small sibs really don't like too much weight down aft, I'd give serious consideration to a 2 stroke. They're so much cheaper as well

Liking your thinking. Commercial use only ?

Get a two stroke all day long. Especially if you putting it in the back of the car. Your bound to put it in on the wrong side at some point and then the oil will cause an issue. A two stroke is much lighter and you can just throw it in the boot (not quite throw, that would just be silly, ).

Had a 8hp Merc 4 stroke on a sib and that was bloody heavy at 38kg, ok for a very short distance (a few feet), but soon got very tired of doing it.

Then caught the rib bug and well the rest is history...... or a re-mortgage (if i had my way), but the wife, oh the wife.

I think your wrong, i'm sure a four stroke has more torque, in fact yeah defo it has. If you look at motocross bikes a four stroke can run on tick over where as a two stroke would just stall, hence more torque.

Correct me if i'm wrong.

I'll guarantee you're wrong. It's not the same deal as with motorbike engines.

See here (bigger engines, but it makes no odds)

Depends on many things not just what stroke the engine is. The 2 stroke will always give quicker acceleration which together with weight will support towing better at that HP IMHO

speak again to the dealer but bear in mind he wants a sale and that cannot happen if he says 2 stroke is better!

Perhaps a compromise is in order.... Go for the 3 Stroke

Take the advice of all the posts, SIB+2S= ! Have to ask one other thing though, unless there is a *really* good reason for buying new and again being a bit of a 'stuck record' get yourself a 'used' rig from the dozens listed every week on eBay - for the dealer price of just the boat *or* the engine you will easily find a barely used boat in as new condition complete with a last generation 2 stroke and probably a trailer too from people who bought new and used it half a dozen times - if it doesn't work out then you can sell if for the same money and see if boating or that particular combination of SIB/HP is for you - most of us on here didn't get the right boat the first time.

Buy a new boat and new engine and kiss goodbye to 30% + depreciation as you load it in the car...
