Thanks everyone for all the help so far!!
We got the motor
55 - 60 gallons of water thru it - and some of it 'looped' from catching it out the exhaust in a 50 gallon trash barrel...
Ran it about 15 minutes. We were pure comedy gold - comic duo racing
around the boat and grabbing more water... We could not figure out how to turn off the motor!!
We assumed the key turn would do it. Nope.
the key out of ignition. Nope.
i frantically started pulling 1 2 and 3 wire off the ignition key area hoping it would kill the motor. Nope.
Thinking a live battery
We thought of cutting fuel but I didn't want to get air into system...
So while me and friend were racing
around to get 2-4 more gallons at a time I frantically raced thru the Yanmar
manual... found a remote
engine kill pull. But of course it did not show where on the boat it was!
I thought the termination looked like this spot low on the motor, and in a panic traced the lines out the back of the engine room with my eyes and saw 3 cables
going back up to above deck
control area... Damnit... scan all over again the 3rd time... I only see some black lock switch which I assumed was something for the rudder
Anyway I finally yank that up... and near disaster averted. Motor stopped.
How's that for funny
for all you experienced sailors? I tell ya, we got it all figure out over here. In two days we know everything there is to know about sailboats and diesels engines! Hahaha!
So then we changed all the engine and gear oil
out with a pump kit. Changed filter. There was much swearing getting the oil
dipstick in multiple times...
In goes the Shell Rotella T 15w40 2 qts of it. The oil coming out was pretty dark / nasty.
Then we ran the engine for about 30 minutes on the clock. Easy start up when warm, 1 second and fires. Runs really nice and smooth. Not hot at all.
We ran motor in neutral the whole time. Is that why we never got the tachometer to register?
We did see at one point when crusty the ass mechanic
had the motor run at some point it had come on. My friend thinks that may be when he instructed him to throttle up.
Is that how it functions?
That seacock is the cooling
water in. And the valve in parallel is 'open' we drained water out of it as a test while we had the blue / black hose disconnected and in the 5 gallon bucket.
I mapped out most of the water tubes / controls. There IS a black water tank up front (small) and a T valve there to switch to 'tank' or 'O'board' (overboard), so we can do both.
I painted the whole bottom hull
some marine paint
blue. Looks nice. My friend started to teak
oil the inside and said it looks amazing. Then we had to leave the yard.
An EXCELLENT day. We are thrilled with the motor and progress.
