The owner of SMS came to my boat to help diagnose a dampner plate issue. The engine shop across the street couldn't make it that day so Mr Hank Hinkley who ran the marina where I was suggested SMS. SMS owner (cant find his card right now)came right after lunch and stayed for over 2 hours. We chatted up Lehmans...he was as knowledgeable about them as anyone else I have ever spoken to or read.
After 2 hours of runs and tests...and unable to duplicate symptoms....he said he thought it could be a dampner and agreed with 2 other marine engineers that running it till failure shouldn't be an issue. I made it over 500 miles, 16 miles from my home dock before it quit. Towed myself home the next day with the assistance towboat I ran. Good deal for me to reapair at my leisure and home dock.
Even after the 2 hrs of diagnosing and lots of free knowledge and advice...he packed up and refused payment....what a guy! Took care of him anyway as he was worth staying on his good side.
Would recommend SMS anytime...
