Trojan Boat Forum

Your mind was made up when you posted the first post . I EFI engines will help some what . Boy you must know people as you have talk to several major builders between 8:45 pm Friday and this morning .

It your boat and you can't do want you want . The reason I am pointing out the issues with this system for a gas boat is to keep other from doing the same .

How are the gas fumes on the back cockpit going to leave the boat ?? and not get sucked in the engine room ?

BTW the system you have should meet the new specs they new one will not from the info given efi or not its a gas boat

the exhust vents need to exit outside the hull not in the cockpit

I will agee on one point the large vents trojan used on the f 32-F36 in the 70s sure are ugly

Jav are ready to make me a set yet ? LOL

I don,t have a cockpit like some of you guys but speaking of station wagon effect.......
while trolling for rock in Nov. I got to see that my new CO detectors worked. I had the cabin door closed but the top slide was open. All of a sudden I hear "Warning Warning Warning" from below. I ran down into the cabin and all three were going off telling me "210 ppm"
Thank God this was the only time my Wife had not gone, since she usualy is napping that early. I finally had to open up the forward hatch to clear out the fumes.
This is the first time I've had underwater exhaust and I thought it would be better for fumes. Apparently not!!!
p.s. I know that 210 is not lethal, but would have got there eventualy.

Did you have the blowers runing ? at low speed you should . not sure if that would help that proplem but can't hurt

Yep, I'm one of those Dorks that usualy forgets to turn them off up on plane so they are almost always on

The whole object of the vents is to provide "clean, fresh" air to the engine room airflow. Air acts like water. I'm sure you have sat and watched water run in fountains, creeks and steams and how it moves around and over rocks swirling on the back side, through holes in fountains and such. If you haven't, your missing some great lessons. Add to this, warm air rising and cool air falling to replace the warm air. Then add pumps/fans. If you can picture the way water would circulate through your system, whether old or new, you can get a real good idea of how the air circulates and flows around and through your boat. (basic micrometeorology, physics and glider flight instruction). The fresher the air for engine intake the better. The fresher the air for cockpit/passenger intake the better. That said, ugly vents I can live with, sick or even dead family members, no. Just be sure of what you do with an untested, unproven air flow system as to not have a negative impact on your passengers, engine or boat. Think "clean", "fresh" air. More is better. I hope you accomplsh what you are trying for but there is a lot more to consider than just looks. Good luck and keep us posted, maybe some detailed pictures.

Well said Wowzer,

agreed.
