Re: first time buyer
I'd be nervous about engine/accessory access too. As I generally do all my own work, I'd hate to find out after the fact that the center 'toon needs to be dropped for routine service work? Not saying that's the case, but I'd sure want to know more about it, and give it a real good looking over. If you don't feel comfortable making that call, get a 3rd party involved. Maybe one of the mobile service guys that services your boat at home?
If you're going to be trailering to/from the lake routinely, and you can't justify a tow vehicle able to do that easily otherwise, that might give me pause too!
Otherwise, I've had several Mercruisers I/O's that have held up well for years without issue....
