18 SF Repower

After years of faithful service, my engine has given it up. Wondering what people are running on their 18's? Current setup is a 100 HP Mariner, would like to move it up to at least a 115, maybe a 150? All input appreciated.

I'm running a 130 Yamaha 2 stroke, 358 lbs. and it seems well suited. My Dad has been running a 150 2 stroke with over 400 lbs. seems good too, but it is stern heavy-he is looking for a smaller motor since his ocean runner died. Another good used 2 stroke under 400 lbs.would be my recommendation due to ideal weight set-up

Part I's 1987 18 SF originally powered by a Johnson 112. Slightly underpowered. Repowered around 2002 with a freshly rebuilt 1995 Johnson 150 (not sure of the weight). Beautiful power match, however he recently added the "ball" scuppers, and is very satisfied. Hope this helps.

What is the weight of the 140 hp Suzuki 4S? That'd be my first question. I only own OMC 2S's and a Yamaha 4S. Don't think I could go back to the 2S but we all know the transom problems of these beauties. Part II.

The 150 Johnson v-6 makes the 18SF fly. If you have good scuppers, the speed is noticably better than my 130 Yamaha . The 140 Zuke would be a great match too if you have the extra $$.

Yes Snookered, you are correct. With single operators and light fuel loads my brother and I run very competitively. But being the smaller, older brother, after many ass kickings, the 20 MA will run him down. The 175 2S OMC matches quite nicely, as well.

Hey, do you know Briguy from your area? A frequenter of Beer Can along with a friend of mine from the Whaler site. Plan to make a rendevous, hopefully this spring with the 15.

I spent many months there on Manatee Ave. opening the original Manhattan Bagel. Peace. Mike.

Mike-hooked up with Briguy a few times over the last few years. saw him at the yacht club New Years Eve afternoon when I was out fishing with the kids. I met your bud from the Whaler site once @ beer can when he and Brian were there in his Whaler. count me in on a get together. My mortgage bussiness is on Manatee Ave since 1999.

Your talking about "Bigshot" right?

If you can find a deal on a good second-hand 130 Yamaha 2-stroke like Snookerd spoke of, that would be nearly perfect. That was the last engine I had on my 18' and it seemed built for that boat.

Weight is still an issue so I would stick with 2s. Mine had a 115 inline Merc and was pretty good but could have used a tad more. A 115 ETEC seems like it should be a great fit, those V6's are going to be real heavy 2s or 4s.

Yes, Snookered. BigShot, now username is The Judge, after purchasing a late model Pontiac Grand Am, is Nick. I e-mailed, actually forwarded him something sent from my best friend in Jersey, and Nick saw the initials of the sender. Asked if it was a guy he went to private school with in Jersey and he had it right. I have yet to meet him. He is an officanado over on the Whaler site. Hope to use my aunt's place in Long Boat for the Beer Can gig. Mike.
