Would a tiller motor be reasonable with a 13ft whaler set up for remote? Also how much hp would be needed to plane a 13ft, 1968? Anyone experimented with 9.9-15hp on these hulls? Thanks

It should plane with as little as 8hp, with a light load. With two or more people you'll have to move weaght around to get her on a plane, and with much more then that you'll be plowing.

I don't suggest useing anything smaller then 20 or 25hp.

What do you plan on useing the boat for, and how many people and weaght go you want to carry?

I think you can find the answer to this question and possible many others that you might formulate regarding the classic 13-foot Boston Whaler boat in the REFERENCE section of the website.

There is a great deal of information provided in other areas than the forum.

My first Whaler (age 9) was a 13 powered by a 15 HP Johnson. My parents wanted to keep the power down for safety.

The boat ran fine loaded with small kids. We even pulled skiers weighing under 100 pounds.

My opinion is tiller steering would be difficult.

Good Luck.

I had a 9.8hp engine (tiller) on a 13 Whaler of the same vintage. In calm water it would plane two 175 pound men, a labrador that weighed 90 pounds, 6 gallons of gas and decoys and shotguns. It was no speed demon. It ran much better with a 20 or 25hp engine.

I would not recommend a tiller set-up since it is much easier to trim the boat using console steering.

We had 13's with 15 Mercs at sail camp, and they ran great. I think one of them even had a 9.9. That flat bottom works well, once it gets over the "hump" and gets on plane.

My 13' has a Yamaha 25 and has plenty of power for me and a big fishing buddy. I've had it up to plane no problem with 3 guys on board. Sips gas very slowly.
