2 stroke V 4 stroke

Boatinggary89 · 06 August 2016, 13:00

I currently have a Mariner 15 2 stroke and am considering going to a 15 HP 4 stroke.
Has anybody owned both and can give a comparison from a performance point of view.

15hp is 15hp, the power delivery will be slightly smoother on the 4s and its heavier but IMO all the cons of a 4s are outweighed by the peace, quiet and economy.

Just my tuppence but what A1an said pretty much sums up my perspective as well.
Not everyone's view but that's mine.

The only thing is you may find the weight difference is quite dramatic at that size-possibly enough you can't carry it any more.

If you're selling a 2s to buy a 4s, you'll have to use the boat an awful lot to make the saving in fuel up to the difference in price as well.

If it was me, I wouldn't be looking at a repower at 15hp, I'd be looking for a bigger boat.

If the Mariner runs well I'd not seek to add the extra weight of a same HP 4-stroke.

Earlier this year we made a swap to 4-stroke after years with a 2-stroke.... but only as we decided to buy new and upped to 20HP so there was a multiple set of reasons.

I've never found carrying and mixing 2-stroke oil a problem but admit it is loads easier with the 4-stroke... particularly being able to use excess fuel in daughter's car to stop it going old between trips.

Quiet operation at idle and low speeds is impressive and using less fuel... while not being a major cost saving as such... does extend the range from a particular tank size.

I never minded 2-stroke smoke/smell... but don't miss it.
