Blower Location 1980 SN

The original location may have been a squirrel cage type blower screwed directly under the rear deck at a bilge vent exhaust outlet. The fan would have had a flexible hose leading into the bilge.

The best solution (IMHO) would be to attach a flexible hose to the deck outlet leading down into the bilge and attaching an inline axial blower motor. The blower can be screwed to the side of one of the main stringers (use Boatlife on the screws to prevent water intrusion to the stringer). This arrangement will exhaust harmful fumes directly from low in the bilge.

Huh! Yes, it is my opinion and I did not compare it to anyone elses opinion. Given the bukl, weight and cost of the original (assumption) squirrel cage fan, the axial inline fan is a cheaper solution that does the same job of exhausting bilge gases.

If you do not like my solution or opinion you can go the factory route which is why I mentioned it to begin with. It is always ultimately your decision.

Also, this board has always been about helping others out in a civilize manner. I hope it stays that way.

Have you seen how many screws are already anchored into the stringers? Common sense and a bit of sealant prevents damage. Maybe I should have been a bit more clear. You should NOT lay the wires directly on the bottom of the boat, but rather bring 12 volts from the original blower location via the top of the stringer. The fan is mounted high on the stringer. I have used this setup now for over five years and I am still on the same fan with no problems. But, then again, I avoid letting my bilge fill up with several inches of water!

And yes, it is sound advice that has proven to work extremely well.

Well IMHO one is being a bit over zealous, but one thing is being over looked, now I'm not endorsing one or the other but if the fan is in a relocated area say the engine compartment then it is not possible to remove fumes from the rear (gas tank) area without and aditional fan.

79:

I do not think so. My '93 SN has air intakes at the bow (at the base of the windshield) and the exhaust is at the stern. My '77 Martinique is virtually the same.

Also, my Martinique has two exhaust scoops. One is connected to the fan and the other is open with no hose to exhaust the fuel tank area. The intake is ducted directly to the bilge. My '93 is set-up very similiarly.

So on your 93 there are hoese connected to the vents in the bottom of the windshield? and run down to the bilge area also?
