4.50 is a cheap investment vs a new outboard.
And that first start up fog chases away the gnats
Won't ever put any of mine away without. Friend didn't on his 115 Merc and left the boat outside all winter. First trip of the year it puked the rings on one cylinder. Ended up the rings stuck over the winter and cracked. $3500 later the motor had a rebuilt powerhead. Which would you prefer to pay?
Remember, shoot straight and shoot often.
Good... Bad... I'm the guy with the gun.
