Yes, the water temp does come up with the oil temp. Neither are high, just a little higher than I would like to see. Eric was seeing the water pressure go from 30 psi with the drives down to about 18 with the drives trimmed. Not sure of the rpm or speed at which it happened. Again, I haven't driven it yet, so I don't know for sure. I'll find out though.

The water temp only went to about 130 or so and the oil to 235-240. The biggest thing is finding out why the pressure is dropping so much.

OK...lots of questions. Bottom line is this. We just spend a fortune (not a small fortune...but a fortune) re-building the motors/re-rigging this boat for the 4th time in less than 5 years. So needless to say I am a little gunshy when things begin to "vary" slightly. I talked with Eddie while these issues were going on and coincidentaly I was driving down to pick up Triple300's boat from Eddie...so we decided it would be better safe than sorry to have him take a look at it.

The boat was never trimmed past neutral...ever. Water pressures were a little lower than what Eddie wanted to see. Oil temps would spike to 240..then would usually come right back down when neg trim was used to tuck drives. We had also paid for spacers and wanted to give them a try. So, instead of me going through trial and error (and not having the ability to monitor engine data like Eddie does) I decided to have him do some testing. We may keep the 1/2" spacers or we may not...it all depends on water pressure, oil temps...and most importantly speed.

These are small bugs to work out in the grand scheme of things and we will have the boat back this comming weekend with the best setup. Eddie is only an 8hr drive for me...this in my opinion is time well spent to make sure things are 100% right.

Both YMP and FPM did a great job on this build....I just want it to last this time. Im sure all of you who have been following this thread can understand why.

Thanks

Eric

Sorry man...I dropped the ball when it came to video time. Maybe if Eddie has some time this week to take a vid or two he can post it. If not, I will for sure get some this comming weekend.

My bad....

Well it's good to hear that everything was no big deal. I guess you thought you had all the temp/water issues resolved before you left NC - at least you now have integrity, honesty and a really good warranty from Eddie "chicken salad" Young (maybe that one will stick).

Good Luck and great summer boating!

Thanks. When we left FPM it was dark and we had been testing all day. We put the pressure on them to have it ready for Memorial Day. Lil R wanted more time to test...but only so many hours in a day...besides we had a 20hr drive back to MO.

I honeslty dont think this is a big deal...just being safe.

Eddie, Here's a thought, and maybe you have it figured out by now. 1.750 pick-up is more than enough water volume. How about when the drives are trimmed the inlet water pressure from the pick-up is higher than the drive side, so the water reverses out the sea strainer back out of the drives. Put a 1" check valve in and you won't have a pressure drop. If you are running a thermostat- oil -control, isn't that already 212 degrees already?

Never thought of that Mark. That is very possibly what is happening. I want to see exactly what's going on with my own 2 eyes.

It does have an oil thermostat. It starts to open at 190 and is fully open by 210. I have a HUGE oil cooler on it so it should be able to maintain 220-225 under hard running. As long as the water pressure stayed up, the temp was fine. As the pressure dropped, the oil temp would creep up to 230. Not sure how high it would go, but it shouldn't go there in the first place.

Both of my engines run up to 220 or so then pop and drop right down and start over again , they both cycle about the same even at cruise speed .

We were seeeing 230+....

Wow , did it keep climbing or ?
