225 distributors

[Woodstockwizzard]

I have a boat with two buick 225 engines. I want to change the distributors to the high energy pointless distributors and I need help with knowing which if any of these distributors will work

Could you give us more information? Engine type (v8?) and year of manufacture?
I have never heard of a Buick 225 engine. Do you mean engines out of an old Buick Electra 225 (which could have been a Buick 350, 400, 430 or 455 cid)
The only 225 cid engine I know of is a Chrysler slant 6 cyl.
That being said, marine engines retained a non-electronic points and condensor type ignition for many years after the automotive equivalents of these engines went to electronic ignition.
For example I have a 1983 OMC 140 hp, which uses a GM (chevy) 2.9 L 4cyl engine, (which is the same as a 2.5 Iron Duke block) Any auto electronic distributor would drop right in, but the points system is more simple and robust, to fix and maintain, especially if the boat gets flooded.

I have a 69 buick 225 electra with a 430 engine. I was trying to do the same as this guy with the electronic ignition. Do you believe that I should stick with the point distributor?

They are easier to trouble shoot for sure, but there are many companies that make electronic ign conversions for all older cars that deliver more consistent spark and reliability. Reliability of the GM HEI in a marine environmnet took a few years to catch up.
