    fuel tank life

    dub question that probably nobody can definitively answer, but just for conversation.... What is the life expectancy of an aluminum fuel tank? I know of boats that are famous for tank failure due in part to installation design, i.e. starboard tanks on Bayliner 32's. I know of a couple boats...

    question on v drive fluid

    I've got late 70's vintage crusaders with Thermo Electron transmissions and Thermo Electron v-drives. All the fluids look very clean but I want to add a tiny amount of fluid to my port side v drive. I will try to attach pics here of the tag and the v drive. There is a dipstick on forward end of...

    fuel consumption report

    gang...just throwing this out there for fun really. I know that 454 fuel burn can be an issue of concern sometimes. I know for me it is. Past weekend I decided to run my 32' sportfisherman over to Catalina Island and back at a slow speed to see what my consumption would be and I was really...

    Fuel tank grounding

    So as I'm doing a new blower install, I discover the fuel fill ground wire corroded off and hanging. So I start exploring the tank grounding itself and see grounding tab on top of tank (aluminum) with ground wires disappearing into the spaghetti of wires into a bulkhead and no evidence of where...

    454 fuel pump question

    Guys, I have the older 454s with Holley 4160 750 c.f. marine carbs and mechanical fuel pumps. I'm contemplating replacing the pumps with electric pumps, thinking this would eliminate the diaphragm failure/leak possibility. Is conversion to electric a better/safer idea than simply replacing my...

    really dumb 454 question

    I have thermo electron 454's in my old boat. I realize the 454's are gm motors. Recently I saw a boat that had 454's but with Chrysler stamped manifolds. So I'm assuming that it's just a different factory marinization of the same motor? Yes? And since I'm asking.....is there any...

    no spark at all on one engine , related to timing shunt (454 crusader)

    Friends, I have encountered a new problem with my recently installed delco est's. Last week, I was fine tuning the carb adjustments at idle and when done with that, I decided to check once more the base timing and total advance for the heck of it. I have timed these engines several times since...

    what is this in the exhaust stream?

    This is my starboard motor at start up. It clears completely after about 10 minutes warm. It smells gassy but does not leave a slick. Oil looks good on dipstick. My starboard carb needs attention. I notice that the secondary plates are dry at idle but when engine shuts down, fuel seeps onto the...

    3208 ta temp question

    I am helping a friend who just bought a 44' Veneti with the twin 3208's. Hours on the motors say about 2000. We did oil sample which came back good on port side, but elevated aluminum on starboard which "could" indicate cylinder wear. He decided to proceed with purchase without retest. Both...

    timing a new delco voyager est distributor question

    I'm a dummy. Cant quite understand total timing but here is first question. The new delco distributors I just installed include a timing "shunt" to be plugged in to set base timing. I get that. But when I want to increase rpm to 3000 rpm to check total timing, do I remove the shunt or leave it...

    454s with Holley carbs questions about carb operation

    I'm trying to better understand the operation of and tuning of the carbs on my older 454s. The carbs are SAE J1223, model 9015-1. Research tells me they are marine carbs 750 cfm designed for electric choke and (vacuum secondaries?). Engines are running ok but starboard motor seems really rich...

    help with identification and source for exhaust part 454

    Guys, on my older (80's vintage) 454's, I have the pictured exhaust collector on each engine, going into muffler. They are looking suspect and I want to replace them. I looked at fiberglass elbows and various tees to fabricate something, but I was absolutely shocked at the expense of the...
