Iboats is the best!
by Robbie from Niagara Falls, Ontario on June 17, 2016
Well I'm located in canada and there's not a hole lot around here unless you are alright with paying triple the price, so I started searching and found iboats where they have charts to help find what you need, along with great prices and good quality parts and let's not forget the best customer service I have ever delt with, well this is a review for this kit lol and as I said there great quality parts so i well deffintly be buying off of iboats aging in the future and they can count on me to spread the word here in canada thanks again iboats.

Fits 1986 Alpha One Gen One
by Stephen from Greenwood Lake, New York on September 30, 2015
All seals of good manufacture. Small lower shaft oil seal is rubber encased - different than my original metal ringed but installs just the same. Changed that same seal without removing upper half of drive from the boat (must remove lower drive and water tube guide - gasket included in kit). Used a small PILOT BEARING PULLER, a couple of pliers and a hammer to easily remove.

Works great!
by Adam from Bowling Green, Kentucky on March 03, 2014
This seal kit isn't as hard to put in as you think, buy the spanner wrench, read a manual, and it's going to be just fine. I did the upper in 1.5 hours and it pressure tested perfect.
