Hey RB, looking at the engine pics, i was surprised not to see risers on the exhaust, how low is the motor compared to the water line? I was wanting to run the 35* elbows on the Spectra was was affraid of getting water backing up thru the exhaust. Cool looking boats, i looked at a couple of campbells up in the Ventura area before buying the Spectra, something to be said about owning the original, everyone copied Campbel.

Your exhaust question is interesting as it has never been an issue on my rollbar boat, but with these ol skool boats, kinda of makes you go uh ???

So I used a life line and contacted one of my Campbell sources (his boat is set up just like mine, only way nicer). This was his response.

Water can get sucked into the motor if one of the following happens:
1) An engine with a huge or weird cam profile can cause water to be drawn back into the exhaust system, which is called "reversion".

2)The engine backfires and produces suction in the exhaust line rather than positive pressure, and therefore sucks water in.

3)The engine "runs on" after the ignition is shut off, or because of a variety of reasons momentarily runs backwards. These conditions will cause water to be drawn in through the exhaust.

4)When the boat is stopped quickly, the engine goes to low exhaust pressure, and the big back wave which hits the transom can overcome the exhaust pressure and travel back into the engine. This is not reversion, but it has the same effect of allowing water to get where it's not supposed to be.

5)Anytime the engine is not running, there is no exhaust to keep water out. While sitting beached, waves can slam into the transom and go right up the exhaust into the engine. Not reversion, but ugly.

6)When the boat is being towed, the engine is off, and the flaps are held open by the boat's forward motion, and water tends to swirl around the hull and into the open exhaust, and then into the engine. Not reversion, but ugly.

7)Flaps obviously help tremendously in each of the above situations, and I consider them "must" items.

My boat does have flappers, but the engine also sits up above or high enough above the water line that it is or at least has not been an issue for me or my buddies boat
thanks

The heighth of the engine was key, I don't liek the look of the "Snails" but the exhaust is below the water line so makes it mandatory on mine. Thaks for the follow up.
