Trim Tabs on my 12 foot Alumacraft?

[westwind]

What model is your Alumacraft, besides 12 ft? The model # should be on the transom brace, a letter at the start of the serial #

E 1449

The model E is a narrow boat, I’d say it doesn’t have enough displacement at the transom to support the weight at the back. Removing weight at the transom or adding it at the bow are your best choices. A tiller extension and sitting forward might be a good choice. I have a Model A that is similar in width to the Model E, but longer at 14ft. It likes to lift the bow some, without some ballast of a tiller extension. Picture attached.

I am going to take off the 12HP Sea King and put on my ‘5710HP Johnson. I’ll extend the hose on the gas tank and move it forward. I also ordered a hydrofoil on ebay. I’ll try that first and see how that works.

My thought is that you will be less than satisfied with your trim tab effort, but it’s certainly worth a try. Mount them as close to the outside edges of the bottom as possible. The fact is that the E and A models have a very narrow bottom, with an almost canoe like rounded profile. We have only had acceptable results with 5 to 7.5 horsepower engines on those narrow, round bottom boats. You will be much more successful with an Alumacraft model that has an F in the model number. FL, FD, etc. Their bottoms are wide enough to support the engine’s and your weight, while providing a large enough flat planing surface. E models were primarily meant for resort and car top service, with low horsepower outboards. Have fun boating. R.T.

Thanks RT. but it is the boat I have and I need to make the best of it. You aren’t kidding about the “canoe like round profile”. It tilts REALLY easy. I have almost fallen out of it several times. When you accelerate from a idle or stop, it can get pretty squirrely very easily. Scares the crap out of you if your not paying attention!

To solve your problem, install steering wheel in the front and it will work safer. believe me. I know.

I agree, my model A really rows well and is excellent with small motors, My model FL is much better with bigger planing motors. Just a few inches wider but planes much nicer. Trim tabs or hydrofoils don’t really compensate for the width….

Actually, I was tinkering with the idea of building a dash/steering wheel/ remote controls. Something I can easily remove and mount as needed. I just don’t have a dash, a steering wheel, or a remote control.

Scott Parrish added all of that to his 12 foot Sea King boat. I think it runs a 15 hp or more, my big 260 pound carcass in that little boat is a fun ride….
