2 stroke vs 4 stroke prop differences - iboats Boating Forums
2023年4月11日 · The 19 year old Yamaha 90 hp 2 stroke bit the dust. The prop on the 2 stroke was a Power Tec 3x13.5x15 which truned 5200 rpm at wot, which was right in the power range. I re-powered it with a Yamaha 90 hp 4 stroke. I used the prop off the 2 stroke and the engine wants to go over 6000rpm which indicates it needs more pitch.

2010年10月29日 · Re: 2 stroke vs. 4 stroke for a 9.9 yamaha I have a 2003 15HP Yamaha 4stroke. I have removed it from my 15ft Duracraft.

2-Stroke vs. 4-Stroke Torque Output - iboats Boating Forums
2003年5月26日 · Re: 2-Stroke vs. 4-Stroke Torque Output Appreciate all of the feedback! Just couldn't see how the 4-stroke could turn a 26in without having some serious low-end torque and don't see how any 115 could reach 67 MPH. Maybe that was a souped-up 115 because they pushed that 18-ft boat (bigger & heavier than my KW) to 67 MPH & had good hole shot too.

2-stroke Vs 4 on a pontoon. - iboats Boating Forums
2008年8月15日 · Re: 2-stroke Vs 4 on a pontoon. Agree with Rick. The "Bigfoot" makes a big difference on a toon. We have two toons, both with 75 HP Mercs. One is 2-stroke, the other 4-stroke. Both toons see use about 70 days per year. Both engines have been flawless. The older 2-stroke has over 1200 hours. I will say, the 4-stroke uses about 1/3 less fuel.
HP ratings 2 stroke vs. 4 stroke - iboats Boating Forums
2009年8月9日 · Re: HP ratings 2 stroke vs. 4 stroke A horsepower is equal whether it comes from a 2 stroke or a 4 stroke. The 4 stroke is far heavier and at 2 hp it cannot do what a 4 hp 2 stroke can do.
