Limiting tilt & trim!

I have a Mariner 135hp V6 that when it's tilted up to it's maximum catches my ski pole. Is there a simple way to adjust it so that it stops short by a few degrees ?

Thanks for any replies ?

Assume, just pressing the tilt buttom bit less..It's like rising or lowering a electric car window to suit your cooling purposes.

Happy Boating

My Suzuki DF70 has a cam/switch that is easily adjusted (by hand) to limit the tilt. It is located at the front of the engine in the middle of the tilt tube. I would imagine other makes have similar mechanisms???

I had a Mariner 60 that would knock the bilge pump hose out of it's connector and my current Yamaha tried to break all sorts of things if I raise it too high - I got used to both of them and watch when I lift.

Thanks for the replies.

I know it sounds the obvious thing stop pressing the button but it's literally going a couple of cm too far and has cracked the current hood as it fairly shoots up when it comes off the rams. No way to move the pole sadly.
It's only become an issue as I'm having a replacement hood painted and tarted to smarten everything up & you can guarantee I'll do it first time out !!

Sods law in action.

You don't give the year, but I'm guessing that your Mariner is going to be the same as my Mercury.
AFAIAA there is no means of limiting the engine tilt upwards other than by watching it. If that's not an option then you're going to have to come up with something to limit the amount of travel.
Could you put a rubber pad on the part of the pole that the hood hits?
Could you make a stainless steel cable up & attach one end to the fixed part of the transom bracket and the other to the moving part to limit the travel?
I'm sure there's a way to do it with some clever electrickery but that's way over my head!

Under the outboard cover, wire a mercury tilt switch (something like a Assemtech S1016 will handle 8a @ 12v) into the switched wire that runs to the UP relay and mount the switch on an adjustable bracket. Simply adjust the switch angle to shut off the power before it hits the ski pole. The switch needs about 15 degree of movement to work properly so you should have enough travel to activate it.

Mercury/mariner you can buy this plastic thing that clips onto the tilt ram inside the cylinder which limits how far it can extend.

Does mean you have to strip the tilt cylinder but its not a huge job

Mercury does indeed do a spacer kit, but they also do a mercury switch

Thanks for finding those for me & doing the research!

Ribnets brilliant for this type of thing. Out of the two methods I think I'll go for the switch, stripping the tilt ram sounds like it might end up in tears !!!

Thanks again.
