different boat question

A friend has an old BW sled with an old 40hp and that runs a 12 x 15 or so. You might be able to go 17 pitch with a 50hp.

That little sled will be dangerous. Probably hit 45+ if it doesn't flip.

Good luck.

I spent my early teen years on the Anclote river in a 13 whaler with a 55 evenrude, great holeshot but no speed demon and real stable the 13 whaler has a heavy hook in the bottom, the faster you try to go the harder the bow pulls down, we would run on the top tilt pin hole hopping
around until you hammered it and down would come the bow.

Thanks for numbers guys, hopefully I get something and get it going. Was wonder how fast that thing will be but the engine is a 1972 (50 aniv. model!) so im thinking its probably not 50 hp at the prop. And being it rated for 40hp a new 40 hp might be fater than mine. Le me know what you think. Thanks again

I have made 5 or 6 crossings of the Gulf Stream from Lake Worth Inlet to West End, Grand Bahama in a 13' Boston Whaler, with a 35 Johnson on the back. Never as the sole boat, always traveled in company, but it would carry two guys, 4 SCUBA tanks and gear, and a cooler full of eats and drinks with no problem, running 20-25 mph all the way across. The trick is to leave right at first light in the summer while the ocean is glassy, and come back the next morning.

I took the SeaCraft Seafari over the same way many times, but with it I could leave mid-day and not worry about the afternoon wind chop from the seabreeze.

Well my neighbor gave me a 13 x 19 that I thought was too much prop so I called our local prop shop. And he said given the light weight of the whaler and a 50 hp I should be more than fine with that prop. Being that is what he does for a living I will give it a shot, doesnt mean it will work but we will see. As far a "hook" in the hull i dont see it after spending a couple hours sanding and painting and i had a 1978 with no "hook" either. let me know what you think. Thanks

Prop sounds right.

The early 13 Whalers were designed with a hooked hull for greater stability in high speed turns.
If you put a 10' or 12' straight edge against the kelson, with one end right at the transom, the ends generally touch, with about 1/2" gap between the straight edge and the hull about 7'-8' forward of the transom. At top speeds, the angle of thrust can easily overcome that hook, but with neutral trim, 75% of the whole hull length will run wet, rather than just the last 3'-5' you can get with positive trim. At neutral trim, no matter how much power you have, the 13' Whaler will never chine walk; indeed, it cannot.

Thanks for the info. When I hear the word "hook" I think of a old Mako I saw some years ago with a failing transom that seemed to pull the bottom of the boat up. Causing what several had said created a sever hook in the bootom. It was very noticable and the transom was very bad. Thats what I was thinking. Good to know thats how my old whaler came rom the factory back in the day. Thanks guys

Like you I spent my teen years in a 13 ft BW but with a 50 Merc on it terrorizing the Indian Rocks intercoastal area. Lightning fast and very dangerous (I know that now) I took that boat places no adult would ever go but it always came home.

While we're reminiscing, I had a 1962 13' Barracuda with a 60 Johnson. VERY scary. The fastest I ever had it was 63 mph and still had throttle left.
