Could anyone tell me what diameter the (factory) speedometer is in my 1998 270 Fundeck?

I believe it is the "standard" size and not a "monster".

I'm ready to upgrade to a similar sized analog GPS.

Any preferences between Gaffrig & livorsi analog GPS speedo's?

Thanks all!

I do not think they made monster's back then. So unless it has been upgraded it should be the standard size. I have a gaffrig digital speedo. A lot easier to read and you see a lot sooner if trimmig is doing any good or not.

Id that an open bow Daytona in your pic?

Looks awsome, what's the engine / drive?

Would you know what the physical diamete of the speedo is? ie,.... 3-3/8" etc..

My boat is 250 miles away and therefore difficult to measure.

Thanks!

My boat is 185 miles away at moment. I will be back there next weekend.
