Outboard Timing

[winzracing]

Hi...Does anyone know how to change the timing on outboards...I believe when fitting a tuned pipe the engines timing has to be changed...Apparently running a stock engine on a tuned pipe dosent do much if the timing hasnt been changed???? Thanx for any info anyone has

There is no need to alter the motor in any way when using a tuned pipe like an Irwin or similar.

Hey SteveM :D Thanks mate for that info...I was told that I had to get the timing changed as will damaged engine???..Going to leave it as it is..Also do you know what modifications are done on outboards to improve performance..eg cutting the piston on the intake side??? and exhaust on sleeve??? cheers

I've never done any internal mods as I preferred reliability over outright power and I have no answers for you, sorry. I've seen a few 3.5cc motors with the pistons and sleeves machined for awesome power but never did find out what the guy did. :cry:
