Ok, I used to have a Merc 500 and scraped that junker for this Johnson. I just need to know where to put my fitting for my water pressure gauge and the send wire for my tach. Thanks
I don't think that engine came with a tell-tale, you could install one and the tee off of it for your pressure guage. There should be a gray wire in the control harness for your tach.
I am not really sure what you are talking about. Do I just install it near the spark plugs where I did on my old Merc? I am new to boating so I am not familiar with some of the terms. On my old Merc I just took a 3/8" plug out that was right next to a spark plug and installed the fitting that connected to my hose for the gauge.
An engine that did not come with a tell-tale on it has to be drilled and tapped to convert it. It should be installed on the top of the block or cylinder head. If you do a search you will find posts on how to do it.
