outboard long or extra long shaft

« on: May 30, 2007, 09:45:44 am »

We are looking into getting a little 8 or 9.9 outboard for our PD. We have an adjustable bracket for the stern and were wondering if anyone has advice on whether to get a long shaft (20") or extra long shaft (25") for the outboard. Thanks for your help.

There are some interesting geometry challenges in mounting an outboard.
1. Will the basic model you want allow you to tilt the motor out of the water and still not bang up against the hull? You may need to try before you buy. Try in both the lowered and raised positions.
2. If that part works, will a 25" shaft clear the water when tilted up, of even with the mount up but without tilting. You don't want to drag it along when sailing.
3. How does the weight at the stern affect your boat balance? I used to have a boat that sank down at the stern under sail or power. A heavy outboard makes it worse.

4. Will you have room for controls? UP and Down ? Where will you mount the controls in the cocpit ?
5. Motoring when heeled, as in motor sailing will benefit from the longer shaft on one tack. You will have to evaluate how it behaves on the other.
6. Electric Start ? More weight but really helpful.

Been hearing good things about the Yamaha motors built for displacement hulls.

Good luck, let us know how it works out.

I have an Evinrude 9.9 xlong shaft on my D26 ('75). Works great, mounted on a sailboat mount on the port side, with r/c cables leading to the helm.

I have two challenges that I'll share: First, the remote starting button on the motor is hard to reach. I have to stoop down off the aft cabin top to reach it. By sounding off a groan that wakes the dead makes it much easier though. It would be great to create a redundant starting button in the cockpit, but I don't know how to handle the choke from there.

The second problem was touched on by Steve (sfisher): that the motor, transom, and cables tend to not work together. I just bent my throttle cable again and again must replace it. My solution, I hope, will be to make the next one about 2 feet longer so that I have extra cable that will create a service loop. Then, I'll turn the motor hard over before lifting, so that the cable is more parallel to the transom and less perendicular to it. It's a simple fix. I hope it works.

I would welcome any other knowledge or experience. Perhaps there's a cable bracket out there.

I put a bracket on my transom as a backup to use with my short shaft Johnson 5hp. It just barely works but is better than nothing if my Vire craps out.

I don't know if anyone else has this problem but my boat lists to port. Granted I have 2 large batteries and a 12 gal gas tank, plus galley is to port. If I were mounting an outboard it would be on the starboard side.

I mistakenly mounted my transom ladder to starboard so am stuck unless I move it.

Good luck with whatever you choose.
