Re: Using HDPE Piping for a Fuel Fill Line

"balancing" the tanks with a line between them is not a very viable option. ALL openings in the tank must be at the top of the tank only: 183.518 Fuel tank openings. Each opening into the fuel tank must be at or above the topmost surface of the tank . While HDPE may be fine, I have not see...

Re: Reduced zinc/phosporus (ZDDP) in Motor Oils

Without knowing the oil base stock, and the package in the oil you are using, a random volume of some random miracle in a can isn't going to do much beyond adding another gooey-dripping can to the shop garbage bin. The dino oil I use in almost everything is the fleet-farm generic barrel of citgo 15-...

Re: Reduced zinc/phosporus (ZDDP) in Motor Oils

High Zddp levels are just as bad as too low. Once it hits .2% it attacks the grain of the cast iron. According to an SAE paper (SAE document #2004-01-2986), .08% was found to be the optimum for wear prevention back in the muscle hayday. As oil temps went up they increased the content to prevent oil ...

Re: Buick/Rover 215 aluminum v-8 exhaust manifolds

i am a mechananic, automotive and marine, and the 215 and its various family of engines have a singular exhaust port spacing and bolt pattern so the manifolds have to be made to fit that head. it is a sad marine engine fact. i was wondering about tubular headers with water jets at each port as i ha...

Re: Running in a remanufactured V8

Depends on the engine If it's a GM (esp chev/olds) it needs to be broke in at a min of 3Kfrom the instant it starts, to a total of 30 minutes, best with a 50% overfill in the case (even more critical if it has a crank scraper and/or windage tray) and a bunch of EOS. The cam is only lubed by windage,...

Re: Cost to marinize this engine?

diesel/kerosene readily ignites with small sparks. There is little difference between being blown out of your boat, or just slow-roasted as you try to become an ad-hock fireman in a floating trough full of secondary fuels. Look at oil-burning furnaces/boilers, "flamethrower" type manifold ...

Re: Biscayne-power?

Assuming you mean the "470" engine -- Well, I guess every boat needs an anchor. Most have ropes on them, yours would have a fuel line. I hate that engine with a passion... in case it wasn't obvious. Mercury decided they would design an engine -- Well, there is the first problem. Since it's...

Re: Thoughts on Grizzly Tools.

The older Stanley/Bailey are a better tool than the new production, but they either of them are far above the asian copies that have been imported in recent years.

Re: trying to evaluate my 1960 Johnson 75hp.

Not that bad It does not look like a typical lean run. Don't worry about predetonation, you couldn't make those old low-compression engines knock on nitroglycerine. Scuffing like that is typical foreign object/material. I have seen excessively carbonized engines scuff very much like that. The scuffi...

Re: Thoughts on Grizzly Tools.

Their house-brand planes are questionable on their best days, pretty much china-junk, with even junkier irons, poor fit, worse finish. Hit up some pawn shops, and find some old stanley/bailey planes, new irons from lee-valley, and you have a good tool made to actually work. Any of those 80+ year old...

Re: Generator Ideas

venting the housing can be a problem if the generator isn't built for a cabinet type housing. Biggest problem, unless the specific alternator, and engine are not ignition protected, you have the ideal recipe for a floating-ride-in-grenade. Crappy magneto ignition, high tension leads of questionable ...

Re: Life just isn't fair sometimes

The worst part of that boat would be the sound of rustling paper as you drive it, because there is absolutely no way you could be seen in that ugly bucket without a paper bag on your head.

Just who thought using a 3 year old's finger painting as boat plans was a good idea?

Re: More Exhaust Questions - Wet Manifolds

You definitely, positively, absolutely do not want to chill the exhaust between the engine and a turbo - more, no humid gas can be going into the turbo, the turbine would be toast in hours. The header tubes need to run hot. In a marine app they are commonly wrapped with glass fiber to retain the hea...

Re: Replaced water pump impeller - won't shift

Didin't get the gearbox op rod timed to the stem properly. Nissan manual says to put it in FWD, and the lever FWD then assemble, if I remember right, but that way is a PITA to get the fork to slip over the pin, time it for NTRL. Take lower back off, put control in N, and be sure to set lower case sh...
