Hi all,
I have acquired (cheaply) a 2004 Mercury 9.9 Sail Power (Big foot) and I am wondering how it would work on my 1981 Catalina 25? I know that I must replace the existing mount with the 4-spring from CD, supported with the backing plates, so that will be my next project.

It is a HEAVY motor, but I like the Extra long shaft and the gear reduction which seems to make the motor ideal for sailboats. So my only real concern is the weight - around 130 lbs. With the new 4-spring mount and the backing plates installed, will I have any problems with the weight of this motor? Thanks for any advice!

The four spring is exactly what you want, congratulations on finding such a nice motor.

Bill,

The Garhauer 4 spring that CD sells is rated for 100-115 lbs. The Mercury Bigfoot (is it really 130 LBs ? I thought it was more like 115 lbs) is on the high weight end but believe that bracket should be fine. With my old Honda 4-stroke which was approximately 100 LBs, when the bracket was released from the lowest position, the bracket would actually kick up a bit and was very easy to raise the motor to the up lock position. My feeling is that the bracket will also handle the Mercury fine, maybe it will not kick up but you should be able to raise it without a block and tackle. The bracket is robust enough for the motor - I have even stoodf on the motor casing and the bracket and transom mounting was rock solid.

by the way, I used the past tnese with my old Honda 4-stroke because I just sold it and my new motor is supposedly going to be water tested this Thursday (1996 Honda 4-stroke 25" shaft) and ready for pick up. We just had 10-12" of snow dumped on us and so...not sure if I can get on the dock and the boat to install it this week even if motor is ready. new motor is approximately 107 lbs (mainly due to the longer shaft compared to my old Honda).

Bill,

If this motor has the integrated shifter/throttle in the tiller, which I think they all do, then you are in for a treat. Do you know if this outboard has the manual tilt or gas assist?

The shifter is NOT integrated into the handle; rather it is a seperate mount on the forward end of the motor, to starboard of the handle. Also, this motor is only a manual tilt model but I have acquired the "outboard tilter" tool for that purpose and tested it on the cart - works well.
Thanks to all who replied - I am going forward with this project, and ordering all the goodies from CD tomorrow.

Bill,

Rcmd take a look at my website and the motor bracket installation I did. Read the paragraph about checking the two nuts near the top of the mounting plate to ensure the bolt threads are fully engaged onto the nuts. Bracket is great...but some that are shipped may not have full thread engagement of those nuts. If that is the case, the fix is relatively easy. CD said they were going to check all in-stock brackets to ensure the htread engagement was okay but rcmd check out my paragraph write-up and then check the bracket yourself to make sure.
