Newbie with TRS drives, Help!
 

I just bought a 30' scarab with TRS drives on it. I understand these drives are not water cooled like the bravo's. My question is Do I need to do anything special to start the engines in my yard? I have already installed water inlets at the sea strainers so I can attach a garden hose to the engines. The engines are fresh water cooled. I am assuming as long as the transmissions stay in neutral I will be ok to run the engines right? I have some tuning to do to the engines before I drop it in the water so they are gonna need to run for a while.

Thanks In Advance

As long as you have water to the motors you're good to go.

The drives don't need water to run on the trailer.

Thanks for the info, I got it plumbed and running today.

Another stupid question, How do you keep the garden hose from collapsing from the suction of the sea pumps when connected to the engines?

You're limited by the amount of water your can deliver. Usually that's about 5-7 GPM while your sea water pump needs about 30 GPM above 3000 RPM.
You'll need to limit your engine speed to 1500-2000 RPM.
Something you can do to help but not fix is to use a 3/4" hose...but they cost about $50.

It collapses the line even at an idle. I guess I will try a 3/4" hose but I was thinking about just putting the pickup lines into a 55 gallon drum and letting them suck from there instead

Don't use a cheap hose. Get the real good ones.

to keep the line from collapsing you need to open the shut off valve i assume you are closing off on the sea strainer from the thru-hull bottom pickup....this will let some air into the system.....the sea-water pump is creating a vacume....been there done that! :D

I am shutting off the valves just befor the sea strainer. Should I be concerned with allowing air into the system, Won't it damage the sea pump impeller's?

As long as you have a decient water supply the pump can pass air with no problem...its when they run dry and heat up when the damage occurs. I work for a pump company...we tested the merc pump to see if we can adapt something along those lines in our product line....you would be VERY surprised at the amount of water the stock pumps can supply! And with a little lube (dish washing detergent in our case to get it started) they can pump a nice amount of air too!!! :D

Saw," Newby w/ TRS, Help," Thought, heck thats Me, read all and was enlightened, Thank You, I have a trans. leak, it seem to be back out at the transom, is there trans. fluid going to the trs drives.?

where exactly is the fluid comeing from? if its pink trans fluid then its probably a rear seal leak and youll most likely have to pull the engine/trans out to do it right. If you have gear oil leaking then it can be you drive...there is an oil passage through the transom to the drive. You have a small oil res on the right hand side of the transome plate on the inside of the bilge area where you can top off the drive fluids...

its defanitly trans. fluid, leaking big time, there's a puddle back in the transom,i guess i'll have to pull everything,Oh well,
Thanks Wally

Since you have to yank the drive off anyway to get the whole thing back together later....yank it off first and take a look at the rear through the transom assembly.....see if your crafty enough to try and fix it that way....i would take the easier route and yank it myself :D

i was thinking the same thing, anything is better than pulling the engine, i'm not very experianced with this stuff. I know a guy who is, he's been out of town, should be back later this week, i think he can do it. I can help Thanks Again!
Also,probly dumb question, but, my fuel pump was dumping gas into the carb. thru that little hose , was told pump is bad,
replaced it myself this morning, checked my oil its over full,
would tha bad pump, pump gas into the engine?

A ruptured diaphram in the fuel pump will result in gas going into the tube. That excess gas might be flowing by the rings and filling the crank case. Or fuel can fill the pump and flow into the block through the pump rod pasage.
Either way, replace the pump and change your oil before you try to start the engine again.

Da yea ,I felt liquid in the engine when i went to raise the rod, it wasn't oil,thats when i checked the oil, way over full, thats when i came here Thanks rdoactive
