Author Topic:   48 HP ON A 13' ?

Steve posted 03-10-2000 02:27 PM ET (US)
Just bought a used 13 with a tired 35 on it. I also own a Johnson 48hp Special in ex.cond. I'm not a speed freak, and have other Whalers. I know its rated for 40hp, but the 48 weighs the same as the 40, ~185lbs.? Mabe 70lbs. more than a 35? Is the weight too much? Any experts out there? Thanks. Steve. stevicki@ptd.net

Steve: I wouldn't worry about it. I ran a 1958 13' with a 1970 Merc 50HP for two years. Boat handled it like a charm and would do about 45mph. My guess is that the 48HP OMC is no stronger than the Merc 50, and boat will handle it easily, if the hull & transom are in good shape. I assume the 10 year warranty is off anyway.

Steve, the 48 will work fine... just be careful!! A friend has a 13 with 48 Special and it runs great... very fast ... oh yes, you can't enjoy the boat's potential without trim and tilt... am assumming that your 48 has it... happy Whalin'.... clark

I run a 50 Tohatsu with power trim and a 15 inch prop on a Dell Quay 13 (a near twin to a Whaler 13) It runs 49 mph with one person aboard-really give a wild ride when trimmed up. I have outrun all sorts of larger boats. This boat is rated for a 50 instead of a 40 like a Whaler, but is the same length, width, and type construction as a Whaler. I would like to hear from Whaler owners familiar with "English Whalers" as Dell Quays are known.

Power trim is very valuable on a boat as light as a 13 Whaler. In order to get full performance potential and to save your back I would consider it a necessity. I had a 13 Whaler with a 40 Merc for 16 years- without power trim and was amazed at the difference when I switched to a rig with power trim. The trim helps eliminate torque steer which can be outright dangerous on a 13.

The weight of the 48 is not too much in my opinion, although the boat may squat a little at rest and you may get some wake in the boat if you slow down to quickly (more so, obviously, if you have the notched transom). For your info, last summer I saw a earliest configuration (no smirk, notched transom) 13' with a 3 cylinder 70 hp Johnson. Wow. I think the 3 cylinder OMC engines weigh in at about 230, give or take 10. I can't recall whether the transom had been built up to 20".
