I have the 33c cable to Merc adapters you may need....

Still want that pump? don't know where to send it... 

one more thing knocked off the long list... just need to look at some diagrams to wire up the relays with the trim limiter to the switches on my throttles... not quite sure how all that works.

so just the up/blue relay goes thru the limiter?  i dont have a "trailer" button.  so down/green goes direct to the relay?

as far as the supply, ground will go to block ground and the 12v will come from the common lug on the perko, starter is too far away, plus the starter comes from the perko anyways. ill use like a 4/6 gauge, its a short run.

rexmar billet trim switch that came on the throttles i bought.

its basically a spdt switch.

so up goes thru the limiter, im guessing limiting how much u can trim while driving so u dont lift the drive out of the water while under way or something stupid like that... then the trailer switch bypasses it to get the drive out of the way on the trailer. 

sound like if you're not a moron u dont even need the limiter and its just more trouble than its worth... just dont hold down the up button while doing 100mph. 

what about trim sender?  ground one side and the other goes to the gauge?

Yep, the trim sender is as straight forward as a fuel gauge, works the same way, the senders aren't very tough though. Just a carbon wiper.

And you are correct, you really don't "need" the limiter, just makes it so you don't raise it too much and makes the boat a little more morn proof...
