[QUOTE="reedjj, post: 191646, member: 4585"] That is what I was doing. The only ones I could use as a reference were the Mercury 25hp and 40hp four strokes both rated at the powerhead NOT the jet. That puts them at 18hp and 30hp respectivley. Yamaha and Honda both have factory jets too but none have 40hp at the jet they are either too low or too high like the 90/65 Merc Optimax or the Honda 90/65 jet. The boat is rated for 40 hp max. So the Tohatsu MD35 is the closest factory jet to the mark with a 3cyl 50hp powerhead and 35hp at the jet and only weighs 197lbs. I like the idea of the 3 cylinder tohatsu over the 2 cyl e-tech. I had a 3 cylinder tohatsu 40hp prop and it was a workhorse of a motor. Like I said before the Merc 40 fourstroke is really only 30hp...And its a 4 stroke and weighs 223lbs. I would much rather buy a motor with a jet already on it. I don't want to buy a good motor and then have to spend another $1500.00 on a jet unit too. But if its cheaper that way of course I will. Its funny to me that the older OMC's are more powerfull than the supposedly new and improved e-tech. I thought it was supposed to be the end all be all of 2 stroke power technology? Maybe I just bought into all the hype about it. I don't have a problem running an older motor if its in good shape. Sounds like a 50hp-55hp OMC with a jet unit is the way to go. I really don't want a 4 stroke motor. The whole purpose is to be light, fast, and shallow. The merc 40 jet weighs almost 30lbs more than the Tohatsu and has 5hp less at the jet??? Thanks Lil Blue Rude and turner032. Im going to start looking for the OMC's Johnsons and Evinrudes. [/QUOTE]
