I put this on with what I believed to be the stock prop and it a 14 5/8 x 17p Solas on Alpha 1. It left about a 16'th inch clearance. So I replaced it with high performance anode and it took a shorter bolt.

Q:
Need propeller shaft seal MERCURY pn. 26-98283 1983 25HP?
A:
Unfortunately we do not have a cross reference with that, you will need to contact Mercury.
Q:
Is this the shift shaft for the lower unit for an alpha one gen one?
A:
Yes this is for Alpha One, not Gen II outdrives.
Q:
Is this the bearing the shifter housing in type2 lower unit?
A:
This particular one is on the prop shaft. It is part #57 in this exploded view: http://www.iboats.com/Mercruiser-Gen-II-Lower-Gearcase-Assembly-Exploded-View/dm/view_id.272971
Q:
Does this come with the o-ring gasket?
A:
Yes, the plug and the gasket come together.
Q:
Is this the gasket for the screw where the gear oil goes in the lower unit?
A:
That is right. It is designated for the drain area where the oil enters the lower unit.
Q:
What is dia. of center hole and width of fins?
A:
The dimensions are as follows: Inner Diameter: 0.875" Outer Diameter: 2.368" Height: 1.325"
Q:
I have an early 2000's Mercruiser Bravo drive mated to the 6.2 MPI engine. I just purchased this boat, it has a Mercury propeller and the/a hub shock absorber with 9 equally spaced recesses for a tab lock washer to mate with. The current washer has 6 symmetric tabs and is obviously not right, as only one or 2 of the tabs line up, and don't allow the locknut to be torqued. What is the correct lock washer? Thanks.?
Q:
How do i replace item?
A:
Identify the OEM number and see if it cross references with this part. If you need some assistance give us a call at 1-800-914-1123.

How do i replace item #2 speedometer tube? Does it just screw into the housing?

Q:
Where are dimensions? 87 Mercruiser 3.0. is 3.5" diameter. What do I order?
A:
Length: 7", Diameter: 6-1/2", Width: 6", Height: 3-1/2". We can only cross reference OEM number so we would need serial number to access parts diagram. This should work if you have the Alpha Outdrive. Contact us at the number at the top of the page and we can look into it further if needed.
Q:
What do you have to fit a 2003, 50 hp johnson.2 cyl small gear case?
A:
This particular trim tab is best for Honda/Mercury applications. We unfortunately do not currently have anything that will match your Johnson application.
Q:
My new prop is a 1/4 inch to far up the prop shaft. The old prop had no spacer, does this washer make the new prop fit right or do I have the wrong prop?
A:
These tab washers are for keeping prop nut secure. These do not act as spacers or anything. You will need to contact us with your motor and prop number you have for us to look into a possible issue. Call us at the number at the top of the page.
