Thru hull raw water inlet for Penta 275

[swampyankee2]

I have an older Trophy hardtop 2459 with 5.7 and Volvo Penta 275 I/O. It has an engine mounted raw water pump with water inlet via the lower unit. I suspect the water neck at the top of the unit is perished and allowing air into the system as the engine runs hot only when on a plane.
There is a thru hull just off to the side of the keel, formerly used for a live well. Can I use this for a raw water inlet since its virtually right next to the raw water pump at the front of the engine? I may have to enlarge it to 3/4" and add a scoop type strainer, but it could eliminate the troublesome water neck fitting on the I/O.

Go fast boats use thru hull pickups often. So long as you install it correctly should be no issues.

Would also need to block off or divert

I believe yhou can still get the fittings your looking for @Scott Danforth can advise

Spend the $18 on the right fitting. Or get the upgraded plastic one. That fitting is a replace ever 2 year deal

A thru - hull fitting for a live well does not work well for a motor supply
