Trim Switch...
 

I just ordered a "on the throttle" out drive trim switch. does anyone have any hints or comments on installing it . it will be one switch operating both drives.

You'll have to use a relay or diode to still be able to trim independently with the dash switches.

Be sure that you use diodes. (Depending on your current dash setup) Otherwise you will not be able to operate them separately.

Me type to slow.

I will be installing it on a 91 311 formula . it now has 2 trailer trim switches and 2 reg.trim switches.

Just put one on the Scarab Sunday. I found it to be a pretty easy install. Wiring was simple and straight forward IMO. Just used the supplied diodes, some heat shrink, and the job was done. Works great! Mine was a single though.

Haven't water tested it yet to see if I'm gonna like it. It looks like it's gonna get in the way of the shift lever just a little bit though.

i am thinking of the same thing for my formula 272.
but my pumps don't quite run the same speed, so i will install two throttle switches. wondering if forward (finger actuated) or side mount (thumb actuated) will be easier for two switches.
i have to hold one of them 1 extra second to have the drives parallel.

Just installed one on my Powerquest with a single. However I did not receive any relay or diode. I wired it off the trim switch in the dash and it seems to work fine. Any idea why the diode or relay are needed??? Mine was a gaffrig switch.
