The great engine debate part 2
 

I posted the paragraph below several months ago about needing to repower my little boat, with all the comments I got about tohatsu outboards I will more than likely go that route. Farting around on the tohatsu website i see that the four strokes and two strokes weigh the same, in that case is there any advantage going one way or the other. gear ratio in the 4 stroke is 2.08 and the 2 stroke is 1.85, other than having to go with a different prop because of that are there any advantages?


Its time to repower le bateau, I have a 16x48 semi-v alweld with an omc 40hp tiller handle, with power trim and elec start. I'm wanting to repower with a 40hp to be able to go into the lacassine pool, and i want to keep power trim and elec start. I'm a yamaha man and have been looking for my unicorn, a steering motor that was converted to tiller to keep power trim, yamaha doesnt come with power trim in a tiller. Since my search has been going on for a while now I'm beginning to think of other brands that could suit my needs. I looked into the E-tech's but they are significantly heavier than the yamaha. I also looked into the suzuki, and on paper it looks pretty awesome with a bigger displacement and similar weight to yamaha, but you don't see anyone around here running small suzuki's. I WILL NOT PUT A MERCURY ON MY BOAT. So the big thing about this post is I am looking for input from people that have experience with the three motors, evinrude e-tech, yamaha 4 stroke fuel injected, or the suzuki 4 stroke fuel injected.

I have a buddy with a 50 Suzuki 4 stroke, had it for 5-6 years and loves it. I've never heard much complaints on them even back in the day, other than the old 2 strokes were thirsty.

This site has about 4 members constantly talking good about the 40 4 stroke tohatsu and I wish one of my friends would buy one so I could drive it. Yhey are cheaper, but if you have the money I would make a good bet the Yamaha is better and has way more warranty service centers.

Depends on how you define "better"? The yamaha is a 40hp unit, no upgrade, it is what it is. The tohatsu is their 40/50 unit, upgrades by pulling the restrictor plate. The Yamaha is a 3 cylinder 45ci engine, the tohatsu is a 3 cylinder 53ci engine. Like they say, "there is no replacement for displacement". Not sure what Yamaha warranty is, the tohatsu has 5 year warranty, and the dealer here removes the restrictor before you take delivery. Again, define "better"? I have run Mercury's 40hp 3 cylinder 45ci unit, nice, but it sure is not anywhere near as strong as the tohatsu. Not even close!

does the 40 four stroke tohatsu have the restrictor plate too, i thought it was just the two strokes.

Yes it is built with a restrictor plate...... But


Lake Area Marine.... when they get in the engines, the first thing they do is take out the restrictors plates.

What year was the Mercury 4 cyl efi that could be flashed to a 60..or 64?

I have had the Tohatsu 40 4 stroke for a year and absolutely love it. Went from a ported 40 merc with 60 carbs and haven't missed that thing. The trips that took me 6 gallons of fuel take me about 3 now. I lost about 4 miles per hour. Big deal lol. I run this motor on a 1650 Xpress and it is a heavy boat. Me, all my fishing gear, 24v trolling motor I run 37-39. No more mixing oil, no more loud motor and smoke. I can't say enough about this motor. Oh, and Lake Area Marine pulls the restricter plate for you so you now have a 50! You won't regret it.

Pretty much any Tohatsu, Mercury, or Yamaha is almost the same when 40hp or under. Tohatsu is usually cheaper plus they build Mercury and Yamaha small engines for them. 4 stroke is the way to go, they are quiet and fuel consumption is a lot better.
