After our first day out which was very good but also tiring, I made the mistake of putting my 20hp Suzuki wrong side down in the back of the car. No oil seems to have spilled but what will have happened?
While I'm not familiar with your particular motor, laying it wrong side down could allow oil to go places internally where it shouldn't be going. That said, I wouldn't necessarily expect it to leak oil externally. If it were me, I'd contact a Suzuki marine dealer and ask them how to proceed before running it again.
Check your manual - some actually tell you what to do. Usually the drill is: stand up right, remove spark plugs, turn over several times, top up oil level, clean and refit plugs, start engine (may be harder than usual), expect it to smoke like a 1970s two stroke for a while.
The risk if you try to start it without doing this is there is oil in the cylinders which can't be compressed and so if you try hard enough expensive bits will bend!
Spot on advice from Poly.... it is so important to give any excess oil a chance to blow out of the plug holes. You can hang a rag over the engine to stop any excess oil splattering everywhere when the plugs are out.
Also if it doesn't start after 4-5 pulls with the plugs back in you might need to take the plugs out and clean a second time.
Here's how it went. Knowing there is a decompression system to ease starting I slowly turned it over to see if there was any hydraulic lock, then faster and I checked the oil level to make sure the level was correct. All seemed ok so I connected the flush muffs and it started second pull without any smoke. I tried it out on water today and all was well. Hope this helps anyone else with this engine.
