OMC 140 Prop help

[smokinbucs]

I have a 67 woodson 18 foot semi tri with OMC 140 outboard not sure of year of motor was told a 92or3 but no tag. Boat has hard time getting on plain but once (if) it does then she'll haul but the tach or any other gauges dont work either so im not sure of rpm range or how to ajust anything VERY new to boating boat floated and ran paid 1000 seemed like a good deal. ANY and ALL HELP will be grewatly appreciated

No data - not much help available. You need to read the "Read this first" sticky at the top of this forum. Prop selection is a crap shoot with data and just a wild guess without it.
