I think I finally found a good boat that's priced well/fair

Leakdown will be a waste of time, It will be pissing air out the valves so hard you won't be able to tell how much is getting by the rings. Better off borescoping that cylinder.

Hmmm, bore scoping is new to me. Everything I've read says to get a leak down test.

I assume that means putting a camera in the cylinder? If yes is that pretty straight forward for a mechanic to do?
 
plug hole. Obviously the head needs to be reconditioned if you purchase, but a damaged cylinder would be a far more expensive repair. Borescope should tell the story. Valve jobs on marine heads is a very common repair.
 
Just had a good conversation with the mechanic for the "rust and corrosion boat". The seller did not have full canvas on the boat. All of the scuppers were plugged and the hatch drains were getting overwhelmed with rain water, falling onto mostly the port engine, thus the wiring harness replacements. In addition the floor board was starting to sag and slope, causing more water to drain into the engine compartment and on top of the engines.

The seller added full canvas, which resolved the water issue but left the boat with a lot of "gremlins" they had to chase down. He says he thinks he got all of the them, that's it's a good boat mechanically. He added supports for the sagging floor. This is a little concerning to me. He said there was some wet plywood as well he recommended the seller replace.

We do a Lot of borescoping in our aerospace business; mostly to inspect for system contamination and look at internal things like valves and instruments. The borescope equipment we use is in the range of $5K to purchase; the pictures are in many cases interpretable due to magnification, lighting, and distortion. So, I'll say that unless you have a dedicated professional do the inspection with good equipment you will be left with more questions than answers. Stick with the leak-down test. If it is blowing through a valve, you will know that and off comes the cylinder head. Another "trick" is to tap the valves with a hammer and see if they will seal due to sticky stems.
Concerned with cylinder corrosion or piston ring issues? Then a quick visual using some optical instrument but again you will not come away with any substantiative data.

HARD PASS….Move on from this one. The one with the low compression cylinder would be WAY more appealing to me. My .02

Yeah, agreed, not a fan of water damage.

Low compression broker will not respond, which is what he did the first time a few weeks ago.
 
Let this thread by a reminder to those buying right now; do your due diligence. If you see/hear something that concerns you, ask questions, dig deeper. A lot of what's on the market is not good.

This was yet another lazy broker who I had to push on to get information. When I recently asked for pics/video of the engine compartment to see the rust/corrosion he was not willing to help. When I asked for the context/backstory he said talk to the mechanic or have someone look at it. So I asked for the mechanics #. Took him 2 days to get back to me, but he did. The mechanic told a great story.
 
What boat are you looking at with the low cylinder? How low is low? How much money? Lot of abstracts here.

2004 Cruisers Yachts 370 with twin 8.1's approximately 600 hours. When my offer was accepted the selling broker told my broker one engine only hit 4200 RPMs recently wide open throttle. I said fine, let's continue, contingent on engine compression check. After scheduling the engine compression check the seller's broker then told my broker the engine checks had already been done by the seller, prior to accepting my offer, and one cylinder tested at 130. I then asked for a leak down test. Never heard back from the seller's broker then, this was three or four weeks ago, so I moved on to the next boat, the rust and corrosion one. My broker's been trying for 3 days again, still can't get a response.

Actually it’s a shame cause thinking about it 130 isn’t all that low which is probably why it hits 4200. Could be something you live with until it’s time to deal with. Leak down should tell you what you need to know. Assuming the broker isn’t inflicted with covid, he’s an ass.

Who was going to pay for the compression test that was scheduled?
 
I talked to the "rust and corrosion" boat broker today and shared what the mechanic told me. This is the same broker who after I shared the amount of rust/corrosion mentioned in the service invoices said "oh that's normal for this area". Strangely he seemed to know all about the water/rot/corrosion issues now and even volunteered a couple of repairs another mechanic did, again with "this is normal" kind of wear and tear. Another waste of my time boat broker.
