Bigger Engine

I have a 2005 2 stroke 60hp TLRD and I want to upgrade to a larger 4 stroke. I would like one in the 90-150hp range. I assume that my steering and throttle cables will transfer fine, but what about my tach? Trim? Hour? and Oil guage/alarm?

If your gauges are Yamaha gauges then they will work but would have to be reset for 4 stroke engine.

Yamaha Guages

Yes it is a Yamaha guage. What does it take to reset it for a 4 stroke engine? I have the "multifunction tachomoter" with trim down the right, tach top center, temp and oil level across the bottom.

Change the dip switch in back of tach to four stroke engine and 12 pole alternator. Set the three switches to up,down, up.
