Don't post much since selling my Hatt, but I thought many would appreciate the following. Am land bound for another fourth...sigh!!! Enjoy yours. Navigational feat……….. The passenger steamer SS Warrimoo was quietly knifing its way through the waters of the mid-Pacific on its way from Vancouver...

Anyone have any experience with using an oil additive to stop a rear main engine seal leak? If the crankshaft has some corrosion contributing to the problem, chances are dim that any additive can help. Engine is a 1970's Cummins VTA903.....Engine was unused for about four years. Runs well...

I am posting this mostly for people who may be reconsidering a repower, but owners/operators with wet risers might also take note of the author's comments regarding such designs. Some years ago I posted my own preference for insulated dry risers, after I discovered them associated with my own...

Hatt dual shorepower service wiring and VTA903 Cummins part I'm aboard a 1961 61ft Burger with dual 50 amp shorepower service and twin transformers. She has twin 1976 VTA903 450 HP Cummins. We are in the Chesapeake Bay, Solomons Island, Md, Washburns Marina, for 3 mos of refit. The new owner...

Anybody have the current Cummins recommendation for 1976 VTA903M engine antifreeze? And what coolant filter/additive cannister is recommended? Is the recommended antifreeze DCA 2 or DCA 4? It has to meet spec ASTM D-6210 specification [like Detroits]. These have wet sleeved cylinder liners...

Does anyone have a source for small motor brushes?? How do you specify what you want? I just took apart a big RULE brand bilge pump....I think a 2,000 GPH or maybe a 3,700 GPH variety. Since they seem to cost over $225 new, I figured I see why it was turning so slow...obviously not running well...

Stumbled across this..thought it might be of interest. http://2-cycle.mtu-online.com/about/heritage?gclid=CNXs-teLisICFeJF7Aod4wQAkQ

[This updates a post I made some years ago. I can no longer find the original via a search here.] What kind of deep cycle battery is 'best'?....most cost effective? In general, when assessing between battery manufacturers, battery types (wet cell, AGM, Gel Cell) and how deeply to discharge...

The RACOR fuel filter covers on my fomer 1972 Hatt had a turn handle which was unscrewed to remove the cannister top to access the filter cartridge inside. The boat we are surveying/looking at has on the top instead a vertical hex shaped extension, like a hex shaped pipe nipple, about 4", and...

Can anyone recommend a large size opening hatch, likely aluminum framed, for ventilation and light, marine style or otherwise? Maybe 36" x 36" or even bigger so one could fit appliances in and out when required? And enjoy sea breezes otherwise. One possibility is a home type 'skylight'...

Not that anyone needs convincing about lube oil analyses, but here is a current unfolding story. During the survey of 1976 Cummins 903 VTA's we got an oil analysis on one engine with the following SEVERE readings. We do not know the hours on the oil, but it's likely been sitting mostly unsued...

Two questions: Hatteras Reverse Polarity Indicators QUESTION: Did Hatteras provide transformers for shorepower AND a reverse polarity indicator aboard? It's conceivable they did so, or that they only provided reverse polarity indicators with a particular type of transformer, either isolation...

A Twin Disc MG511 [or maybe MG5111] transmission oil analysis shows a level of ALUMINUM and CADMIUM "to be monitored...."abnormal" with unknown hours run time. Report includes: " Suggest monitoring the gauges, vital signs, fault codes and fluid level closely between samples. Aluminum is at a...

I recently observed the survey of an Aluminum hull boat’s electrical system and the surveyor and I were unsure exactly what the “isolation’ transformer aboard [ISOLATION was stamped on the transformer case] provided in terms of galvanic isolation from unwanted shore currents. On board testing...
