Beautiful casting. It is quite tight near the distributor and its wires, you could cut a concave relief for clearance in the casting. Cutting...
When one makes a group of changes, it is impossible to isolate the effect of a single bad change in the group. I tried a lower compression ratio...
That was a good change. Being for a v8 head those useless angled holes would only make trouble. When you filled the holes, what did you use? I...
To some extent, a V-belt driven alternator will act as a vibration damper.
Not that I remember, possibly by the foot and you make up your own. There is an o ring company in Portland (Ore.) I went there and was told that...
I was not getting enough fuel dring idle conditions for the adjusting screws to do anythings I drilled the idle restrictors larger and it helped a...
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.
