Author Topic:   outrage 21

I recentely purchased a 1978 outrage 21 without a motor. When I went to the outboard dealership where I live the owner recomended a yamaha 225 due to the stipulation that I wanted to cruise at 40 mph. Does this hp seem appropriate? I am committed to staying with yamaha for service reasons, and I have been happy with the 3 other yamahas I have owned. the only problem is that 225 hp come in a minimum of 25" shaft and my whaler has a 20 inch transom. what is the proper way to handle this?

Don't put a 225hp anything on a 21 Outrage and certainly not a 25" shaft.. that hull will cruise easily at 40mph, loaded down, in a gale with a 200hp , which is the max rating..
I have a 21 Revenge (same hull but a little heavier with cuddy and windshield} with a 135 Merc Optimax and I can cruise at 35-40mph no problem... my two cents worth.. happy Whalin' Clark...

If you wanted a 20 inch 225 in a Yamaha, you'd probably have to go with their VMAX bass boat model. Problem with that is the cowling with the scoop and wing thing would look out of place on a Whaler. Also, I don't think that the VMAX series has all of the stainless components that the Saltwater Series has. I see many folks around here in the Northeast running the HDPIs now. Yamaha advertises a 200 HDPI in a 20 inch shaft length. I would think the 200 would be plenty for the 21.

One other thing, a fellow in my marina has a 21 Outrage, probably same vintage, and I noticed that he has a 175 VMAX hanging off the back. I always wondered why he had a bass boat motor, now it is clear to me that he has one because it comes in the 20 inch shaft length.

I've the same problem with shaft length. I've got a '73 Outrage, with a 1999 salt water series 200 Yamaha. We mounted it as high as we could, but found that the anti-cav plate is about 2.5 inches below the hull. We're going to solve the problem with a setback plate that will give me adjustment also in the vertical plane.

Even though they make plates that are adjustable while running, usually with some sort of hydralic system, I'm opting just for a manual type.

Right now, mounted way too low, we're seeing solid mid 40's range.

Been happy with the yama so far.


PS - When repowering, make _absolutely_positively_sure that there is no dryrot in the transom. BTDT.

Appreciate the advice. This is a great forum, especially for a misunderstood whalerhead such as myself. Ive been running whalers since my dad first brought one home when I was 8 years old, but I still have a lot to learn. Like how do you know if you have dry rot in the transom? Until today I thought the traansom was made of foam.
