I have a 1974 13 Sport that I bought a few months ago. I am looking to buy a motor and don't know what size to buy. It will be two adults and a child most of the time using the boat. I was told by the local marine store that I should not put anything larger than a 25hp on a 1974 transom because of the age of the boat. I am aware that the boat is rated for a 25-40hp motor but I am leaning towards a 25hp 2 stroke or a 40hp 2 stroke. How would a 25hp 2 stroke push this boat? Is this enough hp? Does anyone have any experience with a 25hp 2 Stroke on a 13 Whaler? Don't want to buy the wrong motor and wish I would have bought something different.

Hello there, I have run a 25hp mercury tiller on my 1966 13' a 1980's motor and had plenty of power with just me and a passenger. Probably getting somehwere in the mid to high 20's and quick to plane. I am currently running a much newer tohatsu 18hp tiller and am pleased with the performance from this motor too. I do not use my 13' for tubing or skiing obviously so the idea of a compact lightweight newer motor works for me. The 13' is a very efficient hull and will plane off with only 9.9hp and two adult passengers easily. Really depends on what you intend to do with the boat. For just cruising and running about a new 25hp would be fine. If you want to carry a heavy load and tube/ski you will want more ponies on the transom regardless what the marine store fellas have told you.

I had a 35hp on my 1966 13' sport and really enjoyed the boat for 10 years.
It would even pull me up on 1 ski by dragging a foot with two light people in the boat and me at 175 pounds back then.

Like brisboats mentions, it depends on what you want out of the boat in the way of performance. You could put a 40hp on it but that doesn't mean you have to use full throttle. On the other hand, if you intend to let very young kids take the boat out, you may not want them to have the 40hp.

In General for a given size engine (not written in stone):
4 Stroke = fishing & crusing (more fuel effcient, quiter)
2 Stroke = faster out of the hole, faster top end (some smoke)

Years ago I ownwd a '60's era 13' Whaler with an older 25hp Johnson. The combination was great. Like brisboats (Brian) I didn't ski or tube with the boat.

I'll add that I now own a '03 130 Sport (heavier than the older 13') powered by a 25hp 4 stroke Mercury and am pleased with this set up as well.

Just purchased a new 25hp 2-stroke Mercury for my 13' 1967. With me, wife, and 2 young kids - it performed great. I don't know the speed but was quick to plane and as fast as we wanted to go. I wanted a lighter weight engine because of the age of the boat. I was a little concerned that the 25 would be to slow but I took some peoples advice of this site and I have no regrets. The 25 is exactly what I needed. Good luck
