Stunning build.
Arse sideways, you did well to point out that the concern over coefficient of expansion is not an issue if using a thin layer of epoxy. I...
Epoxy by itself is too flexible. Additives will stiffen it. I was instructed to use glass microballoons. When I tried to mix them in the...
As dampening vibration was just mentioned (and I'm sensitive to it) i will add that it has never been a problem for me with these boat engines I...
Sean, I agree with your thinking. I did not know the detail you provided about water jet cutting . thanks I wonder how much precision matters...
That is impressive. well done
With the oil scraper loose enough to spin, perhaps the piston could be pushed out at that point but with rusted cylinder walls it might hang up....
what about the part of the piston outside of the hole saw cut? Did it have structural integrity so you could use a long punch to move it or...
Clever to use oil that way.
If the hole that you sawed simply released pressure on the rings, that is awesome cleverness. If I read it properly, does the piston then...
It happened to me when I put rack and pinion steering in upside down (on purpose) turning the steering wheel left and it went to the right, turn...
I read that in restoring a single cylinder stationary engine with a stuck piston, one could braze a grease fitting into a spakplug and pump the...
Randy Dupre ran his Mercruiser engines to around 6500 rpm at Maxton. He experimented with both long stroke and short stroke engines. When my...
Reducing the compression ratio to about 8:1 helped my engines than anything else they ran much cooler with the timing advance that I could run and...
Sean My first engine hydrolocked after 2 yrs use (600 miles). Doing that split the cylinder its entire length so I'd not call it strong. It...
I have a 488 that looks exactly like your free engine minus the water in its oil. The 488 was made in the early 1980s for a year or two. They...
not many, but ok for a boat. my fuzzy memory thinks around 25 amps
Years ago, I found that an early 1970S Toyota Corolla water pump will fit onto a block off plate bolted where the merc water pump was. Run the...
If engine length is a problem, I'd try an electric pump (about $150). You could run it off of a $3 relay and a fan switch sensor. Cheap and...
You can do that, but you don't have to as Pertronix makes kits to install their system. Electronic ignition is better when the distributor shaft...
Their catalog is online so thanks for your suggestion. Variation in thickness can be accounted for by adjusting the timing. I am presently...
Sean, there is good reason to assume that delco distributors of that era will have parts that will interchange with the mercruiser distributors....
Is there a source for the o rings that seal the tube to the oil pump? Specifically, the square cross section ones.
you can make the tool. look in the early posts for that.
I used parts from a 1969 rambler distributor (6 cyl) to add vacuum advance to a mercruiser distributor. The 2 holes should be added for...
couldn't reply as my computer power supply died. Hard to know which kind to buy. Putting engine in chassis today, made a few original mistakes...
The manifold I have is for a Ford 460's left side. Its dump tube comes out under the third opening and the dump tube is inclined downward and...
You are certainly right about the alternator mounting possibilities. Attracting attention? With usa flag tied to the exhaust, it will look like...
Having it dump downward at the front of the engine would free up some room as you could run straight back under everything after you get clear of...
How can one even use the huge marine exhaust? I gave all of mine to the boat shop which sells me the engines cheap. An exhaust manifold is easy...
