Best way to winter prep a 90 HP 2 STROKE

Hello, just wondering how best to put my boat to sleep for the winter. It is a fuel injected 2 stroke. Last year I put Marine Stabil in the fuel and tried to spray fogging oil into the intake. Boat was fine in the spring. Would it be better to run it on a very oil rich mixture for few minutes from a separate tank?
Any chance of damaging a sensor with spraying fogging oil?
Thanks in advance.
 
Do you have a 90A, A2, B, or C2?
If an A or A2, see p75 of your owners manual.
If a B, see p81 of your manual.
If a C2, see p94.
If you don't have a manual, they are available online, from https://tohatsu.com/tech_info/manuals.html

Tohatsu recommends you feed oil directly into the cylinders, not fog through the intake.
Tohatsu recommends you drain all fuel from the tank and filter, OR completely fill tank and add stabilizer. Regardless, you should drain the vapor separator, etc.
 
I bought this motor with the cottage we purchased and it came with no documentation . It is a 2014 2 stroke triple. Thank you for the link to the manual.
Regards, Bob

No. Tohatsu OBs are never referred to by date of manufacture. The emissions tag may be to comply with that years emissions regulations. Find the actual model. Probably a C2.
