Re: two questions mariner 25 tiller model
year is 1994. yes, i am pretty sure you can convert it to a remote control. You will have to either find the parts yourself online or go to a dealer and talk to them about it. Pricing wont be cheap though. I did the opposite of you. I converted my 1992 merc 40 from a remote control to a tiller and i got the parts from the dealer and it was 1800 dollars dealer installed plus the cost of the motor when i bought it.
