I have recently repowered my 1988 21’ Sylvan from a 1982 evinrude 150 to a 2020 Yamaha F115! I will need a new tach for sure! What about other gauges? The controller that came with the motor is an aftermarket 703 with a 10 pin plug and another shorter harness which I’m thinking would go to gauges. Hate to say it but I’m a bit confused with this newer technology! Any guidance on gauges etc. would be much appreciated! Thanks!
