i have a 13 ft whaler and was just offered a 1999 15 hp yamaha w the controls for $575.00. the motor looks and runs mint. just curious if a 15hp is to small for the boat. would the motor struggle to much?

In my opinion - the 15 would be a tad short. I had a 13 sport with a 25 Evinrude which was a good compromise - get it up on plane easily and yet troll at about 1.5 - 2 mph with the engine idleing. But then, I am up in the air about 5000 feet. -- Jerry/Idaho

I use my whaler on open and inland waters. I find that my 40 is good enough, I think a 35 would be ok and a 25 would be beerly enough. Although I often have my boat loaded down. so a 15 for a whaler would be (for me) mindbogglingly slow(although I have read that a 13 can plane with a light load and a 9 horse motor.

I dont know what kind of boating you do, but unless it is in protected waters and for running light loads short distances, I would say that you would be unhappy. For the family, waterskiing or just a boat to have fun in, I would say that you will be left looking for more power. It is a great deal and if your are on a tight budget then it is key, but 15hp would only be good for a one person 13 whaler.

One person or if 2 the other will have to sit on the front hatch. For $575 I would take it and see what gives. If ya don't like it you will probably fetch a tad over $1000 for it and then go get a 25 or 30hp.

I agree with Bigshot. I would buy the motor just because it's a heck of a deal.Then I would resell it and get a 35 or 40.
I have a 35 Evinrude on a '73 13' and it does fine but I wouldn't go with any less hp.

Too small.

We got our '63 13' Sport in '66 with a Johnson 18. With Dad driving + one 13 year old, we could pull a 14 year old on 2-skiis. But you could not slalom. We ended up with a Johnson 33s and 40s over the next 15 years.

I have tried the 13 with 20 (old 360 cc), recent 25 and old 40 (twin) all Mercury.
The first and the lastone would bring it back to original. The 20 and 25 are ok for 2 (max 3) persons but I would consider them a minimal choice (especially the 20 which is fast but has less thrust. The 40 twin (140 lb) makes it a little performance boat and is real fun. The old Merc 402 was a good motor but I never loved it. I have never tried the combination with the really lovely 500 4 cylinder 50 HP (165 lb) which exceeds the max power by 10 HP. Legal and insurance problems apart it should work wonderfully.
In such case I would suggest to avoid placing the gas tank in the stern area, and would adopt a small battery if you get a 500 with external pulling rope. I think the 500 is probably the best Merc ever made!

Dirty dozen,
It is a bit under powered. We had a 13 whaler and it had a 40 hp. Yamaha on it. I can offer you a tad of advice: that is, if you would like to get a bigger engine, go with the maximum horsepower rating that the boat offers. This way you can assure that you will have full power potential for the boat :)

Well everyone with a 40 has an opinion on how underpowered a 13 with a 15 is... I couldn't disagree more. First hand experience here from power ranges 15 to 40. I started out with a 68 13 Johnson 40. It went like a rocket could do anything you wanted. The boat knew that the 40 was there, very weighty and twitchy, especially with one person. The Johnson had some problems so I pulled it and installed a like new 1979 15 evinrude out of the garage for day of fishing. It never came off. It was quiter and lighter making the boat feeled better balanced almost like there wasn't an engine back there. It was a pull start so no battery was required saving more weight and room. It started easily and just took off without alot of complication. Plenty of power for two above average adults. Maybe not for three and it would not pull a 200 pound skier; but, in my opinion if you go out alone (or with two) it is a fine rig. By the way I would go out all day on a three gallon tank and have plenty left over. I would try it for sure... If it doesn't suit you, sell it, and look for something bigger. Then you can write the next article ......Chris
