I am in the final faze of my due diligence on the boat. She has a 1973 440/330hp chrysler motor. Had the compression check today and the results were on the left bank: 112,102,105,108. Right bank: 107,98,100,118.
The motor shows 855 hours on the meter. I am looking for someone who might have some insight on these ratios? Any help would be nice.
Thanks.
Bruce.

The numbers seem a little on the low side. As comparison, I just checked the compression on my '68 F250's 390 (warmed up). The compression numbers were in the 120-140 psi range.
Question: Was the engine warmed up when your mechanic did the check, or was it cold. If cold, the numbers will be lower. But, as long as all your numbers show no more than ~10 difference, then you should be fine. I would say your numbers look like they are pretty good. Let us know if the engine was warm or cold.

Use the info for some price negotiation. If this boat is the right one, grab it & do an engine rebuild project with your kids a few years from now.

The motor compression test was done with the motor cold. They are sending over the picture of the engine tag to see what model and rotation She has.
They said it was within their 15% range of each cylinder. 98? compression?
What do you think?
Thanks.
Bruce.

I think it will run for a long time as is, certainly won't mind 87 octane.
Go for it!

If your mechanic checked the compression cold, those numbers will come way up when its closer to operating temp. Things will seal up better.
I say buy that sexy beast! The only downside to the boat is you will probably be stopped by a lot of people wanting to ask you about it. It will become your ambassador of goodwill. And, for the price the seller wants....jump on it!

I just got off the phone with the owner and it is a done deal!!!! Thanks to you guys! He told me new battery two weeks ago and boat cover, bronze prop, new interior last year, trailer was powder coated.
Nice honest man. Mechanic said they were several new parts, electrical stuff. He said it could use some spark plugs.
I am excited!
Thanks.
Bruce.

It was a great deal for the boat. It was the type of classic I was looking for and seeing the value and care the owners had taken to keep Her together for 40+ years is nice.
I will post pictures when I have Her in the driveway so to speak.
Thanks.
Bruce.
