Ello.
Had my second outing with my new 9.9hp 4 stroke Mercury at the weekend, running in. It's got carbs.
Don't know what there is to say about this but always happy to hear thoughts.
I had a fun time figuring out the raising mechanism - you can part or fully raise it with the ratchet clicking in at a whole range of positions.
But to get it back down to selected 1, 2 or 3 tilt settings (1 being straight down) after raising into the ratcheted positions, you actually need to bring it all the way to the highest position for the ratcheting to... stop ratcheting as you lower it so it can go all the way back down.
But a fun thing is, you can't even begin to raise it unless it's in gear, which means an open throttle.
So, when I found the bow going up somewhat at mid-throttle before getting on the plane (was on the Trent, very slow and flat with no wind), I thought "finally here's an excuse to try trimming my engine" (never bothered with my little 2.5hp).
Ended up with a presumably flooded engine that wouldn't start. I am a long time motorcyclist and have experienced this sort of thing after dropping the bike.
TL;DR You have to raise the engine all the way with an open throttle before being able to lower it, thus flooding the engine. Or am I being dim somehow?
