Will this tack work with a v6 2-stroke Mercury outboard

Asked by: Jeffery Davis
Thank you for your question. No, this will not work, I would recommend getting a tach from one of our Marine lines.

Summit says that although this is a 5" gauge, it mounts in a 3.375 hole. Is that correct? I really want an in-dash tach with recall.

Asked by: MacMan
Thank you so much for contacting us. This particular tach utilizes a step down case and does mount in a 3-3/8" hole. Hope this helps!

Do you have these in 4 inch, the same as your GPS speedo

Asked by: Jimbob
Hi Jimbob, thank you so much for contacting us. Unfortunately the only 4" tach we have anywhere in our catalog is this unit: The vast majority would be either 5", 3-3/8" or 3-1/8", with a few 2-5/8" and 2-1/16" models as well. You can also use the "Size" filter on our search function here: Hope this helps!

Hello What do I need to connect it with my MSD Pro Mag 44 ?

Asked by: C-A.N
Thank you so much for contacting us. On a modern Mag44, you'll be able to use the 9118 tach adapter: It should be noted that this adapter does require the use of a suppression style plug wire. Hope this helps!
