Re: 4 Stroke vs 2 stroke Fuel Consumption
I feel your pain with the fuel consumption of a two stroke. My Sea Doo 96XP with the 787cc engine (modified with heads,pipe,flame arrestor) can really suck the gas.<br /><br />Having said that , you would need over 130 HP on a 4 stroke to equal what your 760cc Yam will do performance wise because of the extra engine weight + extra hull size to carry bigger engine etc.<br /><br />Sorry I do not know what the savings would be in fuel cost. I feel the greatest benefit would be the extended cruising range of a four stroke vs. the 2 stroke.<br /><br />Of course a 4 stroke PWC will be more expensive to buy than a comparable performing 2 stroke, so you will not save money on initial purchase. If a 4 stroke breaks or is flooded, it will generally cost more for a major repair. On minor stuff, no big diff in repairs.<br /><br />I am biased toward 2 strokes in dirt bikes and PWC, but as PWC's get bigger, you need a 4 stroke to move them.
