Re: mercury VS yamaha
I have ordered a new aluminum fishing boat (RogueJet "Coastal"), which will arrive in August 2013.
My current boat (Lund) runs a 175 Verado, which I didn't know much about until I started doing some research. I was not much of a Mercury fan until I ran that engine. I was so pleasantly surprised! That engine is quiet and powerful. And even though hole shot isn't a critical factor for the type of fishing I do, my Verado is pretty quick. Only one problem with the fuel system being corroded with ethanol. They covered it through my extended warranty, but it wasn't without an argument. New models do not have the problem, and mine is now protected against ethanol corrosion.
That Verado is supercharged (which is like a turbocharger) and has an intercooler to deal with the increased piston temperature that supercharging/turbocharging causes.
I have a lot of faith in engineers. In the case of the Verado, the head engineer came from Porsche, which is a world leader in engine design. I don't, however, have much faith in the dealers and salespeople. Not that they are bad people, but so many of them just don't know their product. Since most boaters (fishing) are so technical about their engines, and demand that information, salespeople need to get their act together. Know the product AND how it compares to the competition. This area is so lacking. I have come to realize that I can not rely on statements made by dealerships. And it doesn't matter which brand they sell, they are pretty much the same.
I wish I could understand why the Verado comes with an electric hydraulic power steering. Those power steering units draw lots of amperage. And unless, you set-up a deep-cycle battery power source, you will not have power steering when you are running the kicker. The Lund dealer in Dixon, CA were complete idiots on the issue--and arrogant to boot. A local non-Lund dealership fixed the problem. They are the best.
I also have a Mercury 9.9 Pro-Kicker. Not as impressed with that motor, as it is a little hard to dial into a 1.4 to 1.6 trolling speed. However, Yamaha makes a fuel additive (Ring Free Plus), which was recommended by my mechanic (they are both a Mercury and Yamaha dealer). Once this additive was in the fuel, the kicker instantly ran smoother. It prevents build-up that all kickers can have problems with. I would buy a Mercury Pro-Kicker again, if it was part of a package deal.
I am going with Yamaha on my new boat. Probably the 225hp engine. It came down to a long history of reliability. And they make the best kicker on the market at this time. I did a ton of research, and Yamaha has won out.
So, in the end, I think either will do the job to my satisfaction. Just like the Yamaha a little better.
