Jim:
If it's a Borg Warner velvet drive V-drive, the manual calls for dexron III.
It also says ford mercon or any SAE 10 hydraulic oil meeting the allison C-3 spec. will do.
Send me an e-mail and I'll send you the manual.

p.s. If the trans oil has overheated it can smell burnt.
The manual says that if the oil has reached 190 degrees it should be changed.

Jim:
That blue unit appears to be a Walters remote v-drive. Check the brass plate on the unit. It should be a Walters RV 30 or RV 40. If it is, then you also have an in-line transmission (probably a BW velvet drive) attached directly to the engine. The trans is connected to that blue walters v-drive by a short jack shaft visible in the picture. The Walters merely changes the direction of the shaft. (sometimes they reduce the rotations but these units don't have reverse or neutral so they rely on the BW trans) Walters v-drives take SAE 30 HD straight weight non-detergent oil (4 pints max). Since the oil is not circulating in an internal combustion engine, there is no soot, sludge or carbon so the detergent additives can actually become a liability in a simple gearbox if they foam. The larger round object on top of the unit and on the left side where the red throttle cable crosses, is the oil dipstick. There is an oil drain plug located on the centerline under the prop shaft but you can suck out the old oil through the filler/breather.

The oil cooler is actually inside the unit, not exterior like the trans. The larger hoses entering and exiting carry sea water to and from, so it's strange that oil would have leaked from the walters v-drive. Ask the shop for details. Check the level and condition of the 30 wt oil in the walters. If it's brown you have water infiltration.

It also looks like you have 2 silver colored in-line oil coolers in those 2 water hoses. One might be an engine oil cooler and the other, a trans oil cooler.

Messed up and put this on general board first....


Crew of four arrived last evening about 6pm. We had some brew and hit th' sack( brother Mike in the port v-berth, Danny on th' futon, Gary on a foam pad on the salon floor, brother Merle sat on the weather deck with more brews and carried on complete conversations with himself about midnight 'til about, then hit the other pad on th' floor and y'know where I was if you checked th' pics....)

Started fixin up this morning and everything we touched wound up in worse shape than when we started! The Marine AC was not peeing and we found the PO had put th' pump in backwards. Turned it around, th' compressor fired up and things were really starting to cool down. Merle turned the heater on the galley wall on while the AC was running. The Westerbeke rpm dropped way down and the AC compressor shut down and has not fired up since....the windings seem ok with an ohm meter, the high pressure reset reads zero ohms with the pwr off, the little breaker at the rear of the control box on the back of the AC unit reads same(and was jumped out while trblshooting. New batteries were put in the thermostat on the salon wall and numerous attempts were made to reprogram same.

AC man will be here at 0830 in the morning....

Next we filled the water storage tanks and discovered about 6" of water had flooded the starboard hull as we had left the fill hose turned on , so there is a leak to check tomorrow. Seems to only leak when the pump is on....

The head will not hold water when the bowl is filled with a bucket and only pumps water out when the flush switch is operated(no water in).

The dash panel wiring is messed up - I'll get on that in the morning(no running lites, cig lighter socket or dash lites).

Never even got as far as checking things mentioned in my opening thread. We've screwed up about as much as we can today. More tomorrow...

Went on shakedown cruise one hour up the Illinois & everything sounded fine. Did a 180 at the 7mi mark(1500rpm). ran back down at same rpm and gained about 3mph. Everything was ok until we throttled back to stay behind a barge as we were approaching the marina. Once the load came off the port drive began making a racket that sounded like worn bushings or bad bearings(with some vibration also). I think I heard it from the u-joint/V-drive area. Mike looked this morning and moved the shaft with channel locks and,other than some slop, thinks the noise is coming from under the hull under the engine. A diver is to be here in ten minutes to looksee.

We may have to cross the Mississippi to have this thing out. Polestar marina over there says the symptom sounds like the dampener in the velvet drive....

And the boat is 16 wide instead of 14.

If it is only noisy at idle, it might just be an unsteady engine rpm. When an engine misses at low speed, the transmission slaps and makes a bunch of noise. If there is no noise at higher rpm, you might be ok.

LIVING--- If your running the boat and still LIVING -- YOU MUST HAVE GOTTEN RID OF THE GAS SMELL BELOW!!! Great Sorrydog

Diver Dan took a good look and said nothing abnormal. There is some slop and he seemed more concerned with the starboard than the port(where we heard the noise). He also talked about the slap that happens at idle or rough running engine. Two of my crew are giving it up today. Mike and I will hang around and continue fixing things before heading south.

The insulators on the brush spring in the wiper motor fell apart. We didn't know about the insulators, so we hooked the spring up and made a toaster out of the spring. Had a small rubber band - the motor turns now(until the band melts/breaks). Problem is going to be finding a blade as it is the old style with just a hook. Maybe we can adapt a new rubber refill somehow.
