instead of rerouting telltale would a longer hose do?

[fishfeatures]

I have a 3 cyl 60p '89. I was going to reroute the telltale to the top of the block but I was told that running a longer hose over the top of the block would be easier and provide the same purpose. Is this true? or should I carry out the re route (although I really don't want to drill holes in my motor).

The longer hose is the way mine is routed on my 1987 Johnson 150; it works just fine.

You ever had any over heat problems with your motor Will Bark?

Only when the thermostats went cruddy; replaced them and no problems in five years. Hose works fine running from the bottom over the top and then down to the telltale outlet.

Thanks Will Bark. I'll go with that option so..

I thought the idea behind this modification was to prevent air pockets around the upper cylinder?

If that is the case, I can't imagine how routing the hose up and over does anything about trapped air pockets?

Here's a link to a FAQ dealing with this issue and includes an OMC Service Bulletin specifically covering three-cylinder models. Good luck!

See the end of the original post at the page you suggested ,at the bottom it says

"If you don't want to relocate the outlet to a higher spot on the engine, it is advisable to re-route the hose over the engine block to prevent air from entering the system."

this is the reason for me starting the thread.
