Trim gauge for place diverter?
« on: March 24, 2021, 05:50:49 AM »
I have a new hydraulic place diverter and was interested in possibly installing a trim gauge for it. I read through some old posts on here from 2010 about the hydraulic PD having a potentiometer that you can somehow tap into on the hydraulic pump and use a standard trim gauge vs the expensive pre-made/external kit sold on CP/berkely.

Is this possible, if so how (pictures)?

Personally I don't think it is worth it. Before you spend the money, run the boat. Get it up to about 30-40 mph and hit your switch. As the nozzle trims out you will feel the boat accelerate as the hull frees up. Once you have gone past that point as with my boat, it may start to porpoise a little or start to slow down again. Run the nozzle down a little to get you up in plane quickly and then just start to add up to it, you will know when it is there. It's cool (????) to run with the nozzle up but it doesn't really do anything.

So basically you are saying just go by feel of the boat or turn around rather than relying on a trim gauge? I understand spraying a rooster is all show. I am more concerned about over-driving the hydraulics too far up or down because the trim is already at max setting and I click the switch to request for more (overdrive) because I don't know the exact position.

Depending on your pump, If you need more trim try wedges maybe you’ll stay in a better range of adjustment.
I agree on not needing a gauge, the boat will tell you where you need to be.

You can't over drive the cylinder. The cylinders are basically designed to run full open or full closed, hundreds of thousands of cycles. Remember, they are full of fluid which keeps it lubed and also acts as a shock absorber when it reaches the end of the stroke. As you raise the nozzle you will feel an increase in speed. Once you feel the increase stop you will know that you are there. The actual run time from full down to full up is only maybe 3-4 seconds. I worst comes to worst, have someone in the boat with you and time the full up cycle. You can always look over your shoulder and see where your stream is.

I have a 3 wire steering wheel trim switch. I read online that a lot of people used banderlog relays instead of the diode setup as it is faster and more robust. It seems banderlog is no longer around, what are the alternative to powering the 3 way steering wheel switch or should I just stick with the diode kit?
