Cutting a vent in Bayliner deck

[hutch1nson`]

Hi All
I am fitting an Ebersphacher heater to my Bayliner 275. I am fitting the burner in the hatch under the helm seat and want to cut a vent into the front of this compartment for air flow. This compartment door has a rubber seal around it presumably to create some kind of seal. Inside this hatch there are other hatches which are a good fit but not sealed eventually leading into the cabin.

Is there any reason I can cut a 60mm round vent in the front of this hatch?

water / spray ingress in an open boat would be an issue

That's a useful point, thankyou. Perhaps I need a vent that I can close when the heater is not in use

Indeed (I reckon), as long as you have one that is permanently open elsewhere.

What about the vetus units, allow air but no water to pass.
Unsure of max mounting angle, worth checking.

A louvre vent will be fine.
