We had to repair the port prop a second time because the John Martin found a large log in the middle of the Monterey Bay.

    Hi.  The props worked great.  After repairing the port prop the second time (ouch!) we once again have no discernible vibration from the running gear.  This has not been the case in the past couple of years so we are very pleased with the PROP-SCAN based technology.  I think we can safely say that the boat has never run so smoothly and is most likely quicker, but this last is hard to pin down as we did some hull modifications at the same time that you trued the props.  Nevertheless, we are getting 18-19 knots at 1800 turns which is good performance on this boat as she is presently configured.  She is roughly 55X17 feet and displacing 30 tons or so.  The boat is running a little heavy due to our having installed a flying bridge, mast, A-frame, oceanographic winch and swim step since she came into our possession.





I just wanted to let you know I took the boat out for a short ride yesterday and the prop worked great.  I'll be taking it out for a longer ride this coming weekend to verify everything is OK.   I made about 16kts at 3100 RPM which is where I should be. As far as WOT it made about 3650 RPM, same as the old prop. 

Thanks for your great service! I appreciate working with someone that knows what they are talking about.  I will pass along your shop name to anyone I know needing prop service.

Hi Steve, thanks for getting back to me. The prop is unbelievable. I gained 4kts at the same rpm I was normally cruising at. Plus it smoothed out almost

all vibrations. Next year I think I'll put in a new prop shaft also. It has some pitting starting to show, and I think thats where the tiny bit of vibration I get is coming from. I couldn't be happier. Your the man. If I could, I think I would make you a Saint.

I want to order up a back up prop also. I have the print out you sent me, and when I'm ready I'll give you a call. Thanks again.

The above photo shows a propeller success story we are proud of. The Captain of the Pacific Star (pictured at the right) had become frustrated because he was unable to load his engine and was tired of "fixes and guess work" he had experienced when working with other propeller companies in the Bay Area. Thomas Marine Propeller took the time to listen and gather the information that would allow our Prop Scan equipment to do the job it was designed for. Captain John sent an email after sea trials and told us that we are the only Marine Propeller Company he would recommend.
