I am wanting to trade a Merc 2004 40HP EFI 4 stroke for a Merc 25 HP 4 stroke. Not sure how many hours on the 40HP but it is less than 100 hrs and is in great shape. Also has 3 blade ss prop. Wanting to trade because boat I am buying is rated at 25HP max and want to get insurance but will only cover it if it is a 25HP or less. Thanks.
