That is certainly worthy of consideration, especially with the weight of the 115 etec going up. That is nearly 50 lbs lighter than the zuke. Best weight option in a 4-s now. Thanks for the heads-up captbone. looks nice too...

Got to looking at the merc 115 on the inter web. They offer it with a "command thrust" option which is a beefier LU. May have to take a closer look. Any experience out there with this engine? It's new but based on verado technology.

A buddy of mine is a mercury dealer. I'm gonna have him give me a quote for the new mercury. I've already had a quote for a suzuki 90 and a tohatsu 115tldi. I'll be getting an etec 90, 90HO and 115 quote in the near future and will post comparison $

Merc 4S 25" 115 hp Command Thrust is $8,650 from Ed's Superstore, plus freight, controls, prop. Add this in and you're at about $9,800.

Make sure you have a genuine Mercury service center do the install & rigging, or the warranty is hard to get honored. I suggest making a deal with your local dealer before buying from Ed's. You might get the motor installed for less than $10K AND build a good relationship with your local dealer.

Ed's will do the install and rigging as well if you haul your boat to them. However, they charged a friend of mine an additional $250 over their quote to de-rig and remove his old motor, so if you go that route, bring the boat ready for the install.

Thanks Fr. Frank. Appreciate the info as a comparison to a local dealer.

The Nissan 140 2 stroke motor on my 20 seafari needs to be fixed or replaced. Lost all compression on one cylinder. Anyone running a 90 hp on a Seafari, if so, how is the performance, planing time, cruise, top end? What about fuel use numbers? I am considering a Tohatsu 90 or 115 TLDI motor but will consider others. This thread has been useful. The comments on the Etec and Suzuki 90s have been helpful but have been run on hulls other than a seafari. I am concerned about the weight. Father Frank's experince seems to suggest that a 90 on a seafari might work. Thanks for your ideas.

I've got Franks old boat. The 90 works really well. We go out regularly loaded heavy in bumpy seas. I don't have a flow scan but would say we get around 3 mpg, with a 17p black max prop. The motor needs to be raised a couple inches and will do quite a bit better then. I would say if the 115 is the same weight and close to the same HP, get it. Otherwise the 90 will be just fine and probably burn less fuel.

A 90 should be fine. I have that Yamadog 100 (90) hp 4 stroke. It is fine. I think the corrosion resistance of something better than a Nissan/Tohatsu or a Suzuki would be preferable to me.

5MPG. Because of that, I run a 20 gallon tank, although 30 might be nicer.

Don't dismiss Tohatsu so quickly. The regular 2-stroke is a very popular motor in the Caribbean for commercial uses, and rated as very reliable, with a better reputation even than Honda amongst fishermen. (Of course, the larger Tohatsu 4-strokes are just re-branded Honda motors)

The standard Tohatsu 2-stroke 140 hp runs on pre-mixed fuel, makes an honest 140 hp at the prop, the 25" shaft model weighs only 367 lbs, and costs only $9200 USD in Nassau, Bahamas. You cannot buy this motor in the USA, but you can in Bermuda as well.

Their weak spots have been their tiller arm, which is cast steel, their trim system, which is S-L-O-W but robust, and their under-cowling noise reduction.

X2. I have a Tohatsu 90A on my 18 SC and I love this motor! Tohatsus are like old school commercial 2 strokes. Simple and bullet proof. I took the oil injection off of mine but I've heard that they are one of the best out there. I'd buy another in a heart beat.
