I have a 2005 Blazer 190 with an Optimax 225 on it. It has a stock Servicemaster lower unit and it is on the fritz. I want opinions of whether I should go back with the 1.75:1 ratio or move to a 1.62:1 ratio when I upgrade. I currently have a TXP OT4 25 pitch on it now. Is there any benefits or negative impact to the change? What do you guys think?
