"1972" 318 standard & counter rotating

[circle hook]

I am buying a 1972 silverton 33 foot boat, with twin 318 engines the starbord engine is missing but the transmission is there, are the engines the same but with different transmissions or do the engines rotate different. Thanks Bob

Ayuh,.... It's been done both ways over the years,...

Industry standard has pretty much moved to All lefthanded motors, 'n switchin' gears in the transmissions/ outdrives...

What transmission ya workin' with,..??

Post a picture of your props as well, should be real easy to tell if they turn opposite directions.

dont know what type of transmissions they have but both transmissions are still in place never removed, so i can buy a 318 engine from some one and was wondering if all i need to do is bolt it in, or are the starbord and port engines totaly different. Thanks bob

They are different. The starboard engine turns clockwise as viewed from the flywheel. It takes a different camshaft, crankshaft, distributor and starter.

when looking at an engine is there a way to tell the counter roating engine from the standard rotating engine are the starters, alternator, or any other thing on different sides or are they the same, or how about a serial number, like when looking at a pile of 318's on the floor how can i tell whitch one is whitch Thanks Bob

The only visible indication is the firing order.

will the timming numbers on the viberation damper read in reverse on a counter rotation, and am i corect buy saying that should be the port engine.

The ones I've run into had a standard marking and you just had to sort it out for your self. But I wouldn't want to say that they are all that way. The starboard engine should be the counter rotating.
