I felt it was a little sluggish before. So i put a K&N air filter on and a Hiclone filter which is patented product that works like a mini turbo that sucks the air down the carb much faster. http://www.hicloneqld.com/products.html

There was a significant difference in performance after that. That smoke looking stuff out the back seems to be condensation vapors as i cant smell any oil and no smoke seems to stream/hang in the air.

It does seem to have some dead spots under acceleration so not 100% what that is. Perhaps the fuel bowl that sits between fuel tank and engine needs cleaning as thats one thing i haven't tended to yet. thats probably wrong description. fuel air trap? you know what i mean? like i don't think fuel sits in it but collects any moisture i think.

Also i did some fuel calculations from when i had the boat brought around to rivergate for me from coochie. It uses approx 7ltr/hr at approx 1100RPM doing 7knots/hr towing a 16foot heinz hunter. They towed it around so they could get back to Russell Island after hey delivered my boat. That is some awesome stats
