Re: Towing question
You didn't say whether the boat was an outboard or an I/O or the specific model. The 88 Sea Ray Seville bowrider outboard is 1760 pounds for the boat and motor. The I/O version is 2006 pounds for the boat and motor. Figure another 1000 pounds minimum for fuel, trailer and gear and you are right at 3000 pounds towing weight. I did a quick internet search that says that your 1992 4runner has a max towing capacity of 3500 pounds. With that as the max, I would say you are all right but I would add an auxiliary transmission cooler (if its an automatic), and may consider trailer brakes. Neither of those is hard to retrofit. If you are planning to boat in fresh water, I would go with electric brakes if you choose that option.
