Tiny Tach for a 35hp chrysler

[johnrolf]

I want to add a tiny tach to my 1972 35hp chrysler so I can monitor the rpm's with a new prop. I'm not sure which model I need though. Has anyone added one of these? Also, I am running a 10-3/8 X 11-1/2 prop. I want to move to a 10 - 3/8 X X 10. Has anyone done this and can give me a report on engine performance and speed?

If you go for the tiny tach, get the extension lead too. I didn't and I'm sorry now. Their site explains what you need pretty well.

What do you mean "extension lead". Is that just extra wire so you can make it reach the control panel you want to mount it too?

Oops - I accidentally put this in the wrong message thread. I re-posted it here. <br /><br />[Sorry about the late response - travel and subsequent ISP problems prevented me from getting online.]<br /><br />Thanks for the tip on the TinyTach. Which model do I need for the Force 50 (2 cylinder)? Looks like the TT226NR-1C or 2C, but I can't tell which for sure.<br /><br />Also, it looks like I need to buy a new one every 5 years because of the non-replaceable battery. Has it lasted longer than that for you? (I've had this boat for 12 years, and plan to have it at least another 12.)<br /><br />It seems like there are broken links all over their website. Are they still in business?<br /><br />Finally, when I was winterizing the boat last week I noticed that the terminal block on my engine has a screw for "Tach," with a purple wire going through the wiring harness up to the console. So it looks like a traditional gauge might be able to just be attached to that wire. Has anyone else done this, and what kind of tach have people used for this?<br /><br />Thanks,<br /><br />Rick
