F.L. Motor Mounts

[Pete Meisinger]

I'll try to post a picture but in case it does not work I will try a good description.

I want to align the engine on my Albin. I am not certain one of the mounts was tightened properly when we reinstalled the engine. The "up/Down" adjusters seem pretty straight forward but there does not appear to be any "Port/Starboard" adjustment screws or shafts or any of the numerous adjustment you can see on YouTube.

I suppose the mounts could be loosened from the stringers and the engine pry barred into correct alignment. The stringers are steel and in good condition. I have made some hardwood wedges in anticipation of the job to tap into position and hold the engine while I tighten the mounts.

But I don't like the idea. Am I missing something? Does anybody think I should change the mounts to some with horizontal adjusters?

PS: Not having good luck with the images, I will submit this thread and work on pictures

On my mounts the 2 holes where it is bolted down are different in one is a round hole the other is more of a slot.


That allows for a bit of movement.

+1 We just replaced our engine mounts this past year and have the same. One end is a slot, if you happen to still have that original design...

At first we were going with complicated efforts to rehoist/prybar/wedge engine for some side to side alignment. In the end i found it was actually easiest to just barely take the strain off with my lifting mechanism (readirod coupled to the engine lift points running through a hole in a 4x4 post laying across the salon floor) and physically pushing the engine... hard to find a pry point and it turns out you can push it around a bit..

I’ve always tapped mine left and right and never run out of adjustment range.
But that’s dependent on the original holes.

I’ve had Poly Flex mounts for about 13 years. Showing a bit of rust now but that dosn’t affect their usefulness. They aren’t rubber and that’s why I bought them. Rubber is not long lasting and dosn’t actually absorb vibration. The Poly Flex mounts have an active material that’s more like plastic. I think I see it used quite often on vibration dampeners. Not the white nylon but slightly transparent and in fruit-like colors.
If you drop a ball of rubber on a hard floor it bounces back up. There are flexible materials that don’t bounce back up. They just go “thonk” on the floor or bounce up only a small amount. You can hardly see my engine moving and nothing like an engine on soft Yanmar mounts.
The Poly Flex products are made in Australia.
