Re: tacho question??

If your boat was sitting at the dock, and you wanted to do some tuning with a test prop in place, the automobile unit would be fine.<br /><br />The difference comes with shock resistance and corrosion resistance in actual, prolonged marine usage. The car unit is not designed for either.

Re: tacho question??

Boat/US always has something on sale--if you have one nearby. Or keep an eye on eBay--I bought one of these new Lund 0-7000 RPM tachs <br /><br />(http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=1845631115)<br /><br />from this guy about four months ago, but he obviously has more. I paid about $16 for mine. He is honest, great to deal with and an iboats member. He always seems to have some good stuff--check his other auctions.
