18' Superfisherman performance

[JohnC]

Those numbers are outstanding Fr. Frank! It sounds like the perfect boat/motor package.

Love my 18 with a 90 Suzuki, too. Seems to be a good combo/hp for these boats. Enjoy!

Yes, I did. A couple of people got into a bidding war because of it's immaculate condition and I ended up getting $1800 for it, $305 over my initial asking price.
Another local pastor bought it to mount on the back of his 1977 V20 Wellcraft, which had an inline 6cyl 140 hp Mercury with a bad cylinder.

Out of curiosity what hole did they use on your engine mount?

3rd hole mount. It's what I insisted upon. It's perfect.

I have an 18 SF that is under reconstruction, what would you suggest I get for it hp wise, if the deck is being rebuilt and raised with Divynicell and the transom redone and raised for a 25” engine?

If the cg doesn't matter to you, nor the ride in a chop at lower speeds, than go ahead and put an Etec 150 on it.

While weight and hp were major considerations for me, price was important too, as I'm the priest at a very small parish, and I make just $24K per year from the church, and have to supplement that by working part-time at West Marine.
I think that with this 90 Etec I just happened upon the what may be the ideal combination for me and for the boat.

I agree with Fr Frank. Light is right. I have been running a 1992 Tohatsu 90on my 18 and I have been shocked at how well it pushes the boat. It planes quickly with two big guys in it and will run up to 32 mph. Average fuel consumption is 3 mpg. I’m sure the Etec 90 is doing better than that.

If I was going to put a new motor on my boat, I’d probably go with a Suzuki 90 or a Tohatsu TLDI 90.

Good luck

I am currently running a 2013 Tohatsu 90 TLDI in my commercial skiff. It replaced a 2003 Nissan (aka Tohatsu) 70 TLDI which developed a top-end knock at around 3500 hrs. Both motors got worked hard and put away wet, but never experienced corrosion issues. No gearcase problems, changed impellers annually. The 90 however had FI air compressor problems at 2400 hrs. which I blame on human error on the assembly line - nut securing drive sprocket loosened and stripped threads on crankshaft. When the 90 wears out, I'll probably replace it with a 4 stroke. The cumulative cost of 2 stroke oil was pretty much the same as the additional price of finance charges on a new 4 stroke. These engines require a big battery to turn them over cold. A group 27 is barely adequate. They need about 1000 cranking amps.
