  • Blower placement

    Hi everyone,

    I am progressing with the rebuilding of my 1990 PS 190. One of the parts I got with the boat that was in the big box of parts is the blower. I know it goes under the floor somewhere and then a hose connects it to the vent opening by the left exhaust hose, but I don't know where the blower unit itself is normally positioned. Is there a 'best spot' to put it? Also, would you normally have any hose coming off the 'intake side' of the blower or does that depend of where you mount it?

    Any suggestions would be appreciated.

    Thanks

    Bruce

    Hunter, mine is located on the starboard side of the engine (a bit underneath the engine about midway back). The hose runs straight back along the inside of the starboard exhaust pipe. Hopefully, this picture will help. I lightened it up a bit so you could see the hose. Obviously, the blower isn't visible, but it's connected to the front of the hose.

      In the earlier model boats (since you may have this option) the blower is located above the fuel tank with hoses routed to the accommodating vent.

        You sure Sporty? Seems like it would be absolutely necessary to vent the engine area as the carb (in this case) will be the most likely place gas fumes will come from.

        On my '94 their down by the stringer under the engine. In fact, I believe they might be using the same bolts as the motor mounts.

          As we all know (but seldom see consequences) gas vapors are very volitile. Again, I have seen the results of an outboard boat where the tanks were stored "behind a curtain" in the rear of the boat. Vapors are released and fires do happen.

          I was driving down the road one day and looked over at the local launch area. Just about 100 yards out this is what I saw. I turned around and went back to see what the heck was going on. A guy and his GF were standing there, the guy was wet from swimming. He explained to me about the fire that originated from vapors behind an unvented area. Please excuse the lesser quality of the scan. The pic is getting old. This happened a few years back and I caught it on film. Digital has spoiled me.

            I hear ya' but actually very few fumes come from a carb. However, I'm sure there is validity to both opinions. I was just offering up an alternate place that MC once placed a blower. I'd hate to put one in the floor area of the boat. Water would be my concern but in any manner, blowers are very important but often overlooked as a safety feature.

              In the older boats the blower itself is mounted above the gas tank as in Sporty's photo. But the hose runs down behind the tank to the bilge. This causes the air to be pulled into the bilge from the front intake, run under the motor box, and then gets sucked out the back by the blower motor. Many boats have this design and most blowers move some serious air so I think this would work fine.

              But since the boat in question is different than mine I'd figure out where the blower and hoses are normally for that exact year. I'm sure the answer will be posted shortly.

                  Mine is run just like tex, and Air junky. Under the engine.
                  The hose runs back to the vents at the back of the boat.

                  The blower motors are water resistant.
                  The way mine is mounted, the floater switch will kick on the bilge pump before water gets high enough to get to the blower motor.

                  Hope this helps

                    Thanks for all the replies and pictures. I think I will try to secure it on the drivers side of the motor and run the hose along the exhaust pipe as in the picture from east tx skier. I think it's probably more efficient to have the blower pushing air rather than pulling it.

                    Thanks again for the replies. I'm sure I will have more questions as I put this boat back together.

                      Just a follow up. Looked at my father-in-law's boat this weekend (98 PS 205). A more precise description of where the blower is located is just inside and behind the front, starboard motor mount.

                        Just be careful of the hose. When I removed the rear floor board in my '95 - I noticed the blower hose had colapsed. So - I went to the local Home Depot & purchased some rigid tin drier duct. Now I go blower into a short section of flex, into the rigid (which is zippy-tied to something to keep it from moving around) then back to flex where it bends up at the gas tank to go out. I used 2 pieces of the rigid. Works well - been there for 5 years now.

                          Mine is collapsed a bit, too, but still blows strong out the back. Not a lot of room down there.

                            I recently had to replace some sections of my blower hose and i found that aluminum cans with the ends cut off work very well as the junction between the two mating hoses
