How is that 3wsp primary from stm? This is the new one, How long have you had it I’m on the fence about purchasing one ,worried about harmonics,

For summarizing them do you just put stable in the gas and run for a bit? I also wonder if waiting till fall to change oil is better than doing it now? Any one have any thoughts?

Since my 07 apex I’ve been changing my oil once the season is over, I just think if there are any contamination in the oil it’s better to get it out sooner than later.
Also run some good stabilizer, I have a 2001 vmax 150 outboard and have had great luck with Yamaha stabilizer and ring free added to the fuel, still have 120 psi in all 6 cylinders.
