I have a 1983 13' Sport with the original 35hp Johnson. Running well, however, I have considered upgrading boat - the timing of cash will be the only limiting the current question.

I have purchased a 1990 Yamaha 50hp motor - thinking I might re-power the 13' hull for now (keeping the original motor for replacement when I pull the 50) to give me more fun for the time being. The Yamaha was a good buy at $800 in very nice condition, strong compression and all checked-out by a dealer. The question:

If I wanted to buy a larger hull within the next 1-2 years to take advantage of the nice 50hp motor, would I be happy for a few years if I installed this on a 15' or 17' hull until I can buy a nice 4 stroke larger motor?

Typical use: Minnesota fresh water, Family boating, Tubing, recreational fishing - all around family toy. I have enough other hobbies to fulfill speed needs, so boating is a get away without the need to go full throttle. (Although, the 50 on the 13' will be fun ;~) )

Insights appreciated.
Tight lines...

The 13 Whaler with your 50 hp Yamaha is perfect. I think that you should use it and enjoy it and then sell it for $5,000 on eBay. Without an engine you would have difficulty selling the 13 for $3,000. So I would not take it off of the boat to sell it.

Once you sell it, spend another thousand or two and by a 16/17 hull with at least a 70 hp motor.

Some people are satisfied with a 50 hp motor on their 15s and 16/17s, but if you like to tube and ski you will be running at full throttle all the time with the 50. And even then you will not be satisfied with the power. And the re-sale is not good. So don't do it.

Best of luck!

TroutHunter - If you do a search on repower suggestions for a 15', you'll find alot of dicussion within the past year. I have a 1987 2-stroke 40 HP Johnson on my 15' Super Sport and am quite pleased. With just myself, 12 gallons of fuel, a gallon of oil, and a cooler full of crabs, I get 38 MPH via GPS on calm waters. That's fast enough for me. You can pull someone on a tube with 1-2 people in the boat, but that's about it. Pulling an adult skier isn't a real possibility. But in my experience, the 40 HP is perfect for everything else, including cruising with up to 4 adults. The 50 HP may not actually be 10 more HP, depending on displacement.

I have owned 3 classic 15's with 50 HP engines.
84 Sport w/OMC
87? CC w/Yammie
89 SS LTD w/Honda
All boats ran in mid 30's. My current love, the SS LTD sees 35/36 with a fourstroke Honda and gets excellent fuel economy. Granted I do not pull skiers or tubers.
I used a 15 sport with a 70 HP OMC once and thought it great but considering the extra weight I prefer a lightweight 50.
My 02, free for asking.

Everyone has different needs/wants. My 1976 15' Sport runs just about the same with the old '76 Mercury 500 50HP and my new Johnson 40HP two stroke. A little over 30MPH per GPS (still breaking in) with one person and 6 gallons of gas. I don't yearn for more power - I like good fuel economy.

Thanks for the input. It sure is nice to have these forums - a wealth of knowledge on Whalers sure makes exploring options much less painful and expensive.
Shove off!
