Power tilt&trim

Folks I have two outboards all without factory PTT so have been looking for a second hand unit for each without luck for the sort of money I have to spend.

One option is to buy in from the USA a CMC PT-35 PT-130 unit but again COST + Carriage + import TAX and VAT. Heck more than a outboard would cost S/H.

So as I have access to a full engineering shop I am going to make my own unit.

Is anyone interested in buying into a group buy for the parts as for example the 6"x6"x1/2" 6082 T6 alloy is only in 5m lengths and I can make the parts for 3 units out of the length

I would need to run up a costing but it will be WAY WAY below a import. Only thing I need to workout and source is a trim position sensor limiter. Not for profit only a cost share.

George

It might be a silly question, but if you've got 2 non PTT motors, why not just flog them both and buy one with PTT?

If it's not another silly question, are you going to make the motors too?

Couple of thoughts:

Trim limit - use a pressure relief valve. You stop trimming when it changes note, and removes more electrics that will corrode & go wrong. (and you need the relieve valve on the down side in case you hit an underwater obstruction anyway)

Merc legs for inboards have a standalone motor / pump unit to drive the cyls on the transom. As you are building from scratch, a couple of lengths of hydraulic hose and you can mount it on your transom or under your seat.

While we're on the subject of off the shelf hydraulics, I refuse to believe there isn't a single ram out there already......

Is your swivel bracket man enough for what you are about to ask it to do? - Remember a manual tilt engine the bottom of the swivel bracket rests against the trim pin. Smaller engines are usually designed to be as light as possiible. By going PT (I assume you are planning on fitting the ram where the damper now sits) if there isn't a PT version, you will be putting stresses into the bracket that it was never designed to take. (if there already is a PT option that's not an issue)

For powering it, have a look around the breakers - the Merc units are quite modular - mine is powered by the motor off an Alpha drive leg, but if you are planning on using an "off the shelf" pump, a car wiper motor might work?

Shame you didn't ask this a year ago!

If it's a Merc you're working on, then I have a complete saddle with PTT assembly here from a 1999 Merc/Mariner 50hp 4-stroke that you could buy, if it's of interest.

No I would plan to buy the motors that CMC use in the PT-130 as they are proven, self contained units.
