Here is where an ole DDC tech shines. Pull some side covers off now and with a bore scope, look up to the valves and take a peek. Then hand bar...
Would you have the internet addresses for these boats your looking at? Some of us may even know the boat your looking at. ie;...
Rusted exhaust valve seats and valve stems. Possibly even a stuck exhaust valve. It may start up but that rust on the seats may turn to hot spots...
Please re-read what you have typed. 33 year old 92 engine. 1500 hours, never rebuilt. I'm no expert either, only been working on them my whole life.
Learned the hard way a few times. Owners leave the filters apart when the RO is not in use. Fill their water tanks. next day call me rather upset...
1500 hours on a 33 year old boat? Never overhauled? The cylinder liner O rings can't last that long on a shelf, half that time in the engine just...
When I can not find a tank top fitting to use, I added a T to the fill or vent connects at the tank. Don't forget a potable compatible check valve...
Please search and read the many Detroit threads here on YF. Tomorrow, I'm hoping more Viking kids will tap in on your thread here.
I luv Vikings. I luv Detroits. High performance Detroits (92s) can stretch patience and checkbooks if your not ready. There is no fuel economy...
Are you DDC Savy??
Still a press on long life. If it has the straight log exhaust manifolds, then I'll call it the 550HP. Here is a pirated copy of the DDC cut...
Just a question; Are these the 6V92TIAs? Some higher (620?) HP, DDEC controlled engines? We do need the HP or or better model number (TI, TA or...
Unless you really know better, I'd go with it.. A hand held tach would be the better to compare with. There have been a few Volvo to Garmin...
I know Ocean did that. I hope Viking did not go down that road.
I enjoy your company and don't want any sick sea monsters either. Always good for us to check on our brothers. [ATTACH]
I remember some designs that disabled the starter when oil pressure was up. It could be anything. Until somebody goes down in there with a DVM or...
If equipped, yes, needs to be checked. Mine just pulled the shut down solenoids back. I'm also thinking, neutral safety switches.
That looks simple and clean. Most water pumps have their own internal valves. Your bronze valve may just be extra weight. However, Bronze or...
New batteries don't mean much on a boat. Clean and tight cables last week don't mean much today either. Do you have a volt meter and a third hand?...
I'm assuming a cushion usually covers that seat till heavy fish fighting starts. My short term and temp plan would be to spot clean/prep and pour...
