I would like to tow a 1972 13 ft Boston Whaler/25hp Yamaha motor behind a 1972 53ft MY. I have a single centerline eye on the whaler and two sampson posts on the MY. I would be towing at +/- 9 knots in Galveston Bay and would not see more than 3-4 ft waves typically. Couple questions: 1. Should...

On my starboard Allison M20 transmission, the oil is foaming. The oil level is correct, the transmission holds 135 psi in forward at 1200-1800 rpm, and shifts fine. I have had the return line from the transmission to the pump replaced without improvement. A mechanic suggests rebuilding the pump...

On a 1972 53MY, the shower between the VIP and master heads has developed a problem. It initially comes on and works fine, but if you turn it off and then try to turn it back on nothing happens. If I run either faucet in the VIP or master head for just a second, the shower then will come on ...

On a 1972 8V71TI, I've noticed oil dripping from my " sock " which covers the intake on the port turbo. Motor works fine otherwise. This is a symptom of ??? Larry Seadation

I recently bought a used 32v to 12v, 50 amp converter, the purpose being to keep my 12v batteries from being run down from my navigation equipment when I'm not running my genset. Raymarine estimated my draw from both stations to be around 30amps. My only other 12 volt is a windlass and 8 light...

My nav equipment runs off of 12V batteries which are only charged by shorepower/charger or the gen set. While underway, would like to run without the genset but with nav equipment so was thinking of adding a 32v to 12v converter. The purpose would be to keep the batteries from running down...

Think of having a back-up AC water circulating pump on board. I have a 72 53ftMY with the original four AC units. I have seen pumps that circulate up to 1080 GPH. Any recommendations on how many GPH is minimum/best? Larry SEADATION

On the VIP portlight, the rim that extends beyond the trim ring is broken and chipped. The trim ring itself is undamaged. A complicating factor is that the boat has been painted- the external part of the portlight and the trim ring. I am hoping to replace the portlight but leave the trim ring in...

When engines running, helm volt meters read 36v port and 38v starboard. If this is true voltage, will I damage my batteries? Larry Seadation

On my 73 53MY my aft water tank is leaking. It is coming from the bottom or backside- of course. I have a large area of access to the port half of the tank from above and to the front and sides of the tank. I was first going to determine the level of the leak by putting a stick in the tank...

My starboard 1972 8V71T was idling at around 1200 according to my tach, and I confirmed this with a photo tach. I noticed this after a mechanic installed block heaters. I attempted to adjust the idle to 750 with the idle screw but by the time I eliminated the roll with the buffer screw, I was...

On a 1972 53MY I am getting " clear water" appearing from under the port side of my generator pad and a collection of water around my forward fuel tank. Both sites are well above the bilges. The water appears only when the boat is running. It is not coolant from the generator and a mechanic...

Replacing my original lower helm tachometer with 12 Volt VDO tachometer. I have a source for the tach itself, but the lights require a separate source if I don't want them on all the time. Cannot get a 32 volt bulb to fit the VDO recepticle. My instrument lights are 32 volts. A 32 to 12 volt...

I have the head unit only of a Simrad SHipmate CP32. When I bought my boat 16 months ago the unit worked. After installing a Ray Marine package, the unit indicated that it was failing to receive a signal from the antenna. I elected to abandon the unit. The model number is CP32D B/W. Is anyone...

What should one expect for the lowest " acceptable " compression on a cold engine compression test? Or, are compression tests only meaningful on warm engines and what would that value be? Larry Seadation

On my 53 MY the Allison transmission pressure is read directly- ie, hydraulic, on the lower station. In line, there is a t-peice which a 2-lead VDO pressure sensor is connected for the upper helm. I finally came to conclusion that my sender must be causing the gauge to peg out. When I replace...

Both engines running fine but at idle getting some blackish smoking. Had tune up and mechanic recommended pulling injectors and testing them- a days labor. I was reading the bottles of Seafoam and Lucas injector cleaner and both talk about filling the primary fuel filter full and adding balance...

On my upper station, I have VDO gauges. When I turn the power on to the gauges, the port transmission pressure gauge pegs out, the port engine oil pressure pegs out after 40 psi when the engine is running, and the engine synchronizer gauge pegs out to port. I have rewired the grounds to no...

Ok, I've now had my 1973 53MY for one year and have addressed many mechanical and electrical issues, but not the fresh water system. My port engine bilge insidiously fills with water. It's not coming from the engine compartment, ie, thru hulls, exhaust system, ac system or stuffing boxes. Its...
