MODEL # E20CRESB
I'm going to look at a 20HP ourboard tonight and plan on checking compression and spark and doing a crackle test on the lower unit fluid. The motor supposedly has sat for the last four years in a guys basement so any tips on things to look for would be much appreciated. It's a pull start and I plan on converting it to electric start if I get it so here's my questions...
1) I'm interested in adding electric start and charging. What will I need to do this?
2) Is it just the carb that needs changed for the bump to 25HP or is porting different on the 25 HP as well? If it's only the carb i will probably do this.
3) Lastly, for this motor what would be considered "good" compression? I know you don't want much variance between the 2 cylinders but how low is "too low"
thanks in advance for your info - I will post results if I decide to get it and do the modifications.
