The Black Marlin season has started on the Gold Coast. The young ones come South around October from the Far North. The fish get progressively bigger as the season gets underway. Plus there are lots of Mahi-Mahi, Wahoo and Tuna to keep us all happy. This is a small Black we had to bring on...

What is the ideal operating oil temperature on 12v71n's? When out fishing my Port engine shows an average of 190 degrees at 1000 to 1200 rpm and 210 degrees at 1700 rpm. However the Starboard runs at 200 degrees at 1000 to 1200 rpm and what concerns me is that on the way back home, after 8 or...

Hi Guys, Does any member know where I can buy one of these Prime Pumps? They are 32 Volt "Oberhoffer". I need it urgently. I have one for the Port and one for Starboard. I use the Port regular because the generator feeds off this engine and sometime when the engine is not running and the fuel...

Can anyone email me the Trouble shooting pages from the Allison Gearbox MH Manual PLEASE!

When I purchased my 53 Convertible in 2010, one of the first things I noticed was that there were NO sea strainers servicing the raw water intakes for the engines. When I asked why, I was told the rise of the the intake (almost 3 feet) from the hull and the outer screen were usual in Florida and...

Another failure on Allison Gearbox. The Port side gearbox (MH20) failed last year (forward gear) and was rebuilt. At the time a new Hydreco oil pump was also installed. The boat has been run around 20 hours since then. In Queensland the fishing season has kicked off and I had the boat hauled...

I have asked this question of people who know their boats and the Detroit Engines, but I am getting a different response from a respected supplier of Gear Box oil pumps. I replaced both the oil pumps for the gear boxes last year with NEW Hydreco pumps. At the time, the supplier advised me that...

Hi Guys, I have a question regarding the amount of fuel RETURN on the 12V71n’s. I need a Fuel Return Amount PER GALLON USED. I have a reasonable idea on the fuel burn of the engines at trolling speed, cruise and at full, but I am trying to get a bit more accurate for a week long trip I am doing...

Hi, Can anyone let me know how to get access to the AFT fuel tank on a 53 convertible? From following the lines on my boat it looks like it feed the mid tank but does not have it's own access to the fuel manifold. I am asking because after all the ups and downs of the last weeks, I think I will...

Hi All, Thought I would enhance that beautiful curve on the side of my 53 Convertible. Also, in truth, the paint was getting very chipped and bubbled at the join with the deck so the teak hides it as well as looks good. At least thats my opinion. Let me know your thoughts. I will post more...

How much is “normal” for Detroits Diesel engines to leak oil? I have 12V71n’s. This is my first experience with DD’s and I am not used to seeing much oil leakage in an engine. The Port engine has the leaks. Stbd very little. Each time I have had experienced DD owners and mechanics look at my...

I have finally sorted out the gearboxes and am now sorting out other issues. Mainly refrigeration issues, only the galley freezer works. The refrigeration guy working on the boat has found a couple of leaks etc., but there are bigger problems. I have a fridge in the galley, plus a freezer and...

The Hydreco keeps on being a probelm! I have just started the port engine, the one with the rebuilt Hydreco. At cold start the pressure goes to 260 and oil starts leaking from the filter houseing. After warming up, the pressure drops to 150 and the oil stops leaking from the filter houseing...

New gearbox issues to solve. I have just repaired the port Allison Gearbox, so I was checking the starboard gearbox oil and found the oil was aerated. Then checked the screen/filter and the hose to see if it may be sucking in air and found metal filing behind the screen. After the panic had...

Repairng the Allison Gearbox After my last deep sea fishing trip, I lost thrust to the port side fwd engine. Reverse was still good. After checking various causes, including re-building the Hydreco oil pressure pump, my mechanic said it was most likely the seals in the gearbox and the flywheel...

Hi All, Some advice please. When I was returning from a long fishing trip, I noticed that the port engine revs kept dropping. Checked the port engine throttle/gear control & it had come right out of its bracket. The bracket was badly made and weak. Also now the port engine would not go into...
