Does the whirlaway add an actual 2.250"? I've got a Beaver Fab release and it measures 1.500".

They are pretty much interchangeable. I would say 1 1/2 is a little closer to the actual number.

Whirlaway adds 1 1/2".

There is no stress on them, and they are just basically sitting on the floor held by bolts tapped into fiberglass. But everything helps.

I had about a 1/4" between the coupler and the shaft seal using a rope type seal. I got the log set DEAD NUTS to the shaft angle, shortened the hose to the minimum, slightly trim the face of the log, and replaced the rope seal with the single grease, trimmed the face of it slightly, and now there is 2 split collars with about a 1/8" between the seal and coupler ends.

Not only is the front side of the double seal longer, but look at the hose side!!

aim using the shortest one they have i have shortened the hose some ...can i but it right to the log ? or a little wiggle room ? i almost have enough room to put one in front of the seal right against the coupling

Would a 1/4" cut off give you enough room?If you only cut off a 1/4" it will leave a little bit of that rib.

Yeah, you'd move it. But if he already has 16 holes in the bottom of his boat, I would be tempted to leave it. I'm not one to turn my keel in a perforated "break on the dotted line"

But I would consider taking all but about an 1/8 of the raised should off the log and seal, get the log dead nuts, and shorten the hose to the minimum, and using T bolt hose clamps.

How much room do you have now with out changing anything?
Are you planning on running a collar in front of the strut too?

Is there any meat to trim off the coupler?
