New engine intake thru-hull mounted wrong?!?
My engine was overheating last year, the input strainer thru-hull was corroded and not letting much water in. So I had the boatyard replace said intake thru-hull today, used to be 1/2" scoop (clamshell) bronze, I upped it to 3/4" marelon (also scoop or clamshell). The OLD thru-hull was mounted with the slots facing BACKWARDS. I assumed the yard would install new 3/4" the same way, but of course they put it in with slots facing FORWARD this time. They're telling me this is how it's supposed to be, and there won't be any issues. Is this right?
I'm worried that with a bigger thru-hull that is now facing forward, the scoop will ram more water in than the 'ol volvo can handle (1980 MD7A 13hp by the way) possibly I dunno flooding the engine with saltwater or something ... ?? Dunno.
Oh and they drilled for the scoop holes & bedded it with 5200 so it's going to be a big deal to change.
