Why
run the risk of cracking the lower housing with an impact wrench on some of
those very hard to remove 4 3/8 lower retainer nuts. Guessing where to drill
holes can be a very time consuming and an inaccurate way of doing this. With this
tool you can cut your time in half and not destroy any of the threads in the
lower housing in the process. It will fit all #1 MerCruiser "R"
outdrives including Alpha One "MR", Generation II, TRS and Bravo I. It
will not fit TR, Bravo II or III at this time.
Before !
How would you remove a nut like this ?
Step 1.
Place the tool over the prop shaft with the drill bushings positioned at the
narrowest point of the carrier nut and clamp in place with an old prop nut. Now
drill 2 holes with the 1/4" flat bottom drill to the depth on the drill
stop.
The 1/4"
flat bottom drill and drill stop is included.
Step 2. Now
loosen the prop nut and turn the fixture 90 degrees. Retighten the prop nut and
drill 2 more holes to the depth on the drill stop.
Step 3.
Remove the fixture and punch the 4 separate pieces of the old retainer nut
inwards. Notice there are no marks inside the lower housing threads from the
drill because the 2 life time hardened drill bushings keep the drill in
the exact location.
After !
This was done in less than 2 minutes !
