Author Topic:   Tach or No Tach

I'm getting a new (2002)Yamaha 60hp 2 stroke for my 15 ft Striper. With a new engine, I have the option of getting a tach with it for $100. I have a question as to how necessary a tach is for a 60hp engine. Does it is fall into the value worth $100? What would be the benefits of having a tach and the limits of not having one?

Appreciate all opinions....

I'd say go for the extra $100 and have the'll need it during breakin when your trying to test your engine making sure you're proped right...I'm sure there's other reasons like performance, vote is, it's worth it...(I like spending other peoples I know how my son feels...but it's usually my money he's spending...)

Definitely worth having and worth the $100. The tach besides looking cool in the console will make it easier to prop your boat right. When used in conjunction with trim you can monitor the tach to keep your rpm's within the engines sweet spot, or most efficent cruise. Many other uses too, get it you will be glad you did.

I agree with the other posters, its worth having. You can get a Teleflex tachometer for $60 to 70. Easy to install. You merely connect the three terminal posts of the tachometer to the pigtail hanging from the Yamaha 703 control. All you need is three wires of sufficient length, some crimp-on bullet and terminal connectors, and some electrical tape (about $7 worth of materials).

Consider getting the Yamaha multi-function gauge which provides:

--tachometer (digital readout)
--trim position indicator (grow-bar read out)
--oil reservoir level indicator (3-stage indicator lights)
--engine hour meter

This is probably more expensive than just a tachometer. In any case, a tachometer is highly recommended.

I like having the tach to adjust trim for maximum motor speed. As I trim up, rpms rise until trim is optimum, and if I trim past that, rpms fall.

Well, It is obvious. I'll get the tach. Also, I will look into the multi-function guage. Any idea of cost?

Thank you for all of your replies.

I'll second jimh's response. No idea of the cost (part of the package on my 50), but I really like the Yamaha digital multi function.

Good Luck

Watch Ebay usually you can get the multi function guage new or close for ~$150,

I had one of those multi-function tachometers on my 22 Revenge. I don't think I ever paid any attention to the trim gauge to set the trim of my motor. Speedometer, tachometer, engine sound and seat of the pants are much better for adjusting engine trim.

The oil reservoir indicator is a nice function on that gauge but you can get a Yamaha analog tachometer with the oil level indicator new for less than half the cost of the multi-function gauge new.

I actually like analog tachs over digital tachs. My 'vette
has both, and I never use the digital tach. The only place
I might want digital would be with twins to set them to
the same RPMs.

I too actually like the yamaha analog tach better, but I thought the harnesses were different. If the plug in is the same and you don't want to spend the big bucks go with the analog.
