Author Topic:   Outrage trim

I just launched my new (to me) 78 outrage 21 with a new Yamaha 200 efi. The bow rides pretty high at moderate cruising speeds and doesnt trim nicely until the boat is moving at 30 + mph. When I take her through a 3 or 4 foot chop I cannot trim the bow down enough to mellow out the ride. I have read previous threads about this problem but not any solutions. Has anyone tried using a transom wedge, trim tabs,or planing fin on lower unit with any success? Craig.

I have a '96 Outrage III (19'-8") with a 200 hp Yamaha. I had problems similar to yours with a full tank of gas and a couple of passengers. (No problems with light load). I installed a doel fin just before going moose hunting. I was fully ( and I mean fully) loaded and had to do 60 miles to moose camp. Boat got on plane like a shot. Even loaded some of my buddies lbaggage as he couldn't get on plane.
I was able to stay on step to about 24 mph if memory is correct. (loaded).Once at camp I did about 50 miles lite load. It was a dream.
Returd trip was lite load (no moose). Ran into a bad snow storm with 6' waves.Boat road them beautiful. Go for doel fin.
Only worry is that I seem to recall from this forum that fin increases load on motor lower unit and transom I guess. Hope this does not cause me any problems.

Does the usage of a Doel Fin void engine warranty?

I had the same problems that you describe with my '91 Outrage 22' with Whaler Drive and a Yamaha 250. I installed a Stingray Hydrofoil. It was the best $35 I have ever spent. Hole shot was improved, I was able to plane at slower speeds, grip in turns was improved, and best of all, I could actually have full use of my trim. I actually had to be carefull though that when I hit the throttle hard, that I had to be right with it on the trim, or the lift that was created by the fin would start to drive the bow way to far down. As far as instalation, it took me longer to put the boat on the trailer than it did to install it. I can not speak highly enough about this mod.

I am not sure about engine warranty though. However, something is telling me that I read on the package that it does not. But I could be wrong so you should check it out yourself.

Having been a past owner of a 22 vhull and now a 73 21 outrage, keep in mind that a harder ride is what we're gonna get with that hull. Notice how nice is sits at rest, and minimal roll when walking back and forth between gunnels? Welllll, tradeoff time is a rougher ride, compared to the later models that extend the V all the way to the stern.

Trim tabs or doel fin _may_ work, but I'd want to hear some testmonials.

I'd suggest the wedges first. I believe that many of the BWs of this vintage came with the non-hydraulic (basically spring loaded), tabs, but were often removed since they are only an "ok" design. you can still buy them, but the wedges are so inexpensive and require no new holes (something I like) that they are worth a shot. it makes sense that they should work...

or even better, an engine bracket. some of these brackets add flotation and you can tell them what angle you want to mount your outboard at. but the wedge is probably the best first try...

Thanks for the advice, and hello Don, havent talked to you in a while. The boat has a marvelous ride and I anticipated some pounding due to the shallow rounded stern and midships. My complaint is due to loss of control of the boat due to successively higher bow coming off each wave until the outboard is the only thing left in the water. If the trim could be controled then the boat could be controled - I think. The owners manual dous say that trim tabs are of little use due to the transom design. Since fins are so easy and people have had success with them, it seems like an obvious place to start. Otherwise the boat works great and contrary to the discussion earlier this month on Outrages, 200 horses is just about right, especially loaded down.

enjoy the spring, Craig

If you go with the "fins" or whatever, please post the results.

I have a 71 outrage 21.
since it does ride harsh and will fly off waves, the tradeoff is, SLOW DOWN.
in 3-4 chop I usually just get the boat
on a plane. maybe 18-20mph. and thats it.
and on big waves I'll slow down and/or
make sure to slice it at a diagonal.
thats just the tradeoff. If you want to go
faster you need a different hull.
of course, running WITH the waves is a blast.

Alaska, sorry to say that's the way those slab sides handle in chop or steep seas. One reason BW moved to a deep V in the larger boats in '78 with the 20 deep V Outrage.

If that is the typical conditions you run in would consider figuring out a way to mount trim tabs -- maybe the Lenco's which don't require a hydralic pump --- just a suggestion ---
