The engine is out of alignment with the shaft and coupler. Notice the tight fit at the upper part of the rubber bearing and the gap at the bottom of the bearing. This shaft was way more difficult to turn than it should have been.

Here is Sea Ray #3 for the week: Pre-Purchase Survey and Sea Trial aboard this 2008 350 Sundancer. The black gel coat was in stunning condition. These darker colors are tough to maintain. I identified a list of minor service items, but no deal breakers here. And again, Frank and the hoist crew couldn't have been more helpful and flexible for the hoist-in, THANK YOU.

Sea Ray #2 for the week: Pre-Purchase Survey aboard a 2000 Sea Ray 340 Sundancer with a sea trial scheduled for next week. Needs a good detailing and new electronics, but lots of potential here. Always good working with Dave Selz and seeing Scott Moyer!

It was a near perfect day for a survey and sea trial aboard this 2001 Sea Ray 380 Sundancer. Shout out to the friendly hoist crew at Son Rise Marina for their expert timely service.

Yesterday was a first for me. What started out as a routine Condition & Value Survey for insurance purposes ended very sadly. I found elevated moisture meter readings across the entire transom, around the stern drives, wrapping around to the aft hull sides. Percussion hammering confirmed delamination of the fiberglass from the wood coring of the transom. Sporadic elevated meter readings were found all over the hull sides, especially around any drain fittings and port lights. I had to make the decision to remove myself from the job. The owners who bought the boat 5 years ago (without a survey) were crushed. I didn't make any money yesterday, but I slept pretty good last night.

Interesting finding today: This dripless shaft packing seal was indeed dripping! It was visibly deteriorating and when manipulated, it would visibly drip. Also, there was a tell-tale streak of water stains on the stringer and bilge floor. If you need to replace one, you better replace them both!

Sea Trial this morning aboard the 2000 Formula 312 Fastech from last week's survey. Once the boat got up to 58 mph, I put my camera and phone away so I could hang on while we reached 74 mph.
