RE: [omc-boats] venting the cowling

David,

I do have a question then that you maybe able to answer.

Do you know what density of foam was used/should be used. Under the floor?

I have stripped the hull clean and am trying to figure out if I need 4 lb
foam or what.

Thanks!!

Tom

Charlotte, NC

No, I was not an engineer - I assembled prototypes, worked on molds to build
prototype hulls etc. then took them out for testing etc. very interesting
job but I was there for only a year - then got married and moved away - but
at least I got all the training etc. - even have my Certified OMC Mechanic's
certificate. Dave

Probably never noticed it - during my stint in engineering at OMC I ran a
lot of hours testing on Lake Michigan - there were several other OMC's out
on endurance that ran everyday - I do not recall ever seeing anyone run with
the engine cover off - so it is likely no one ever had the chance to notice
the difference - Dave

So if the engine runs better with vents, now I am wondering why they
didn't put them in originally? Noise? Or is there some special
marine/safety issue with venting it?

It wouldn't hurt anything to put a vent in - but I think I would put it
on the port side of the cowling - where the carb is located since you
wouldn't see it there - Dave

I have a 65 omc deluxe i/o that I know little about. I have been
finding that it seems to be running better without the cowling on the
engine. Perhaps my imagination, but I don't think so. So did those
cowlings ever have vents in that nice flat section of the front that
seems perfect for a vent grill? Would I be screwing anything up to put
one in there? Those little grills in the back seem kind of useless.
 
Thanks for any comments!
