Re: 1958 fastwin

I'm with Joe Reeves on this - the deciding factor is what type of beariings it has. I have a pair of 1958 ERude Bigtwins that have hundreds of hours on them running at 50:1. Neither mtor shows any sign of powerhead problems.

Re: 1958 fastwin

My understanding is that in the fifties the 10-horse and above used roller bearings while the 7.5 and less used bronze bushings. Despite any potential differences in fuel mixture for different engines within a given model year, across the board they were consistant in the fuel mix (be it 16:1 or 24:1).

Here's an interesting photo taken from my 1974 OMC Accessories brochure showing the 3 different OEM tanks offered new that year. Number 1 is the 2.5 Imperial gallon (3 U.S gallon) single line non-pressurized tank ($28.75), number 2 is the 5 Imperial gallon (6 U.S gallon) single line non-pressurized tank ($28.75 + $9.10 for hose and bulb assembly), number 3 is the 5 Imperial gallon (6 U.S gallon) dual line pressurized tank ($48.95) for use with 1949-1959 outboards (it is probably the 1958/59 continuation series). The 1976 brochure also lists those tanks but shows a single line tank incorrectly referenced as a pressurized tank.

Looks like Cam solved the tank mystery. OMC slapped the pressure tank assembly on a single line tank at the factory.
