Outboard engine mount problem

view profile

Newt2768 says:

Hi Everyone,
I have encountered a problem as a new A24 owner. My boat has the original fiberglass outboard engine mount which fits into the cockpit well. In forward gear at merely quarter throttle - the mount (and thus the engine rises). Any suggestions? I have seen on the site that many owners have solved the problem by fitting heavier mounts and/or placing bolts on the walls of the cockpit. But shouldnt the original mount work?!!
Regards

Perhaps a photo of your mount might help. Mine sometimes rises approx. 1 " under load and fits reasonably snugly. I have a 6hp 4 stroke Mariner which is a weighty lump to lift . It all works very well and I don't need a lot of throttle to push the boat except against a big spring tide.

That should not happen.
Is it a long shaft motor?
Is the tilt to much?
Try putting a soft rubber ball behind the motor to take the load against the rear bulkhead.
I have not had this problem in Chille .. or goskar , and not head of this happening before.?
My Tohatsu 8 on Goskar would strain the box under load hence the rubber ball idea.
A long shaft motor is far better than a standard one ,,,,,,,?

Sounds like your engine (which should be a "long shaft") isn't sitting properly in a vertical position. There should be some sort of adjustable stop, or a selection of positions for a transverse bar, on the engine's own mountings for it to sit against when driving forward. In the Achilles arrangement it is not unknown for the stop to fall out, so I hope you haven't lost it. Look where the engine was stowed by the PO.
Loosen the thumbscrews and slide the engine out a little way to check, then adjust / replace the stop so that the engine can barely move fore-aft. If in doubt, choose the setting that will put the prop slightly forward, as that will tend to lift the stern as you motor - but don't over-do this; I'm talking of a single degree or so. The engine's own weight (dis-regarding the mounting plug) should always be enough to hold the assembly down - and motors haven't got any lighter in recent years!

Mine does this too under heavy throttle. The previous owner glued a shim of 3mm or so plywood along the aft end of the mount (under the lip) which made it fit more snugly. Think this helped. I don't think it's much to do with the angle of the outboard, I've tried all sorts. Suspect it's the result of the mount gradually wearing and becoming a looser fit.

Hello everyone, by the way. I bought an Achilles three years ago, inspired by the enthusiasm of the members of this site, and am so glad I did. The forum has been an absolute fount of knowledge - thank you all!

Welcome cejenika.. Where are you?
The Lift ,, may be thrust from the prop. in up down direction as opposed to port starboard mode. .. a pair of bolts would stop that ,, AS my pic, (I did not need them . my boxes were tight) .

Many thanks for the suggestions.
I have a tohatsu 6hp sail pro (long shaft).
I have the varied the angle of the engine including having the engine at it most vertical position - all to no avail. I think in my case - the problem is the mount itself. Going to try the other options suggested - plywood to make the mount more secure or perhaps bolts. ( or maybe even sealant ! )As stated above, the mount has become looser as a result of gradual wearing. Cheers.
Ps great website !

My mount moved with Tohatsu 6hp sailpro ultra long shaft. Bolts were the answer. See pic www.flickr.com/photos/achilles24/7514420932/in/set-721576...

My A24 has a u-bolt mounted on the cockpit floor, a couple of inches in front of the outboard well. I tie the engine mounting bracket to this to stop it tilting up at the front, which I suspect is the same as the problem you are having.
