Happy Easter and Passover to All!

I've worked on engines all my life and I should be smart enough to figure this out but... Our dink has a little 4HP Merc. Today it had great difficulty idling and clearly the carb needs cleaning ( I left it all winter with fuel in it) and adjusting. Here's my problem: It's a manual start...

I have 2 6/71 naturals on my 58 LRC. A mechanic told me I need to only put a zinc in the one place after the heat exchanger. He said to leave the other 2 with no zinc?? (one at salt water pump and one before heat exchanger). Is this correct. ???

We recently purchased a Garmin network bundle and have a question about the XM satellite receiver hookup. Unfortunately, Garmin tech services have been unable to help in this case. The XM signal output from this unit (radio and/or weather) goes to a stereo system via two (black & red) jacks. We...

On my engines the RW connection between the turbo intercoolers and the fuel cooler consists of a curved chrome tube about 2 feet long connected at each end with a short section of hose. Is this oem? In re-installing my intercoolers I was looking at the layout and thinking that full-length hose...

I am NOT repowering - well, not until the diesel electric thing is sorted out - but I'm curious about one aspect of the process. I assume that when Mr. Hargrave, who seemed to know what he was doing, designed most (all?) of the boats we discuss on this forum, the weight of the drive train planned...

My original port tach (lower station, 1972, mechanical) stopped recording engine hours at exactly 2,000. It seemed like one gear did not want to register that even reading and they all stopped. RPM indication remains correct and my Glendenning synchronizer works properly. Any ideas about what the...
