Hi all,
I recently purchased a 1997 Four Winns Horizon RX (this is the Horizon 180 now). It has the Volvo/Penta Cobra SX outdrive. The boat was owned by a doctor and maintained by a local shop including a couple weeks ago right before I purchased it, when he had a new water pump installed along with an oil change and spring tune/lube done.
The boat came with a full tank of fuel. According to the shop that did the work, which I visited, the prior owner did not use the boat last season, meaning there is some old fuel in there. The reason I asked this is because it does not seem to have much holeshot power, and occasionally will backfire, particularly when reducing RPM's from cruising or higher down to a lower speed.
For the power and weight of this boat it should get out of the hole pretty quickly I would think. The shop owner tells me to be patient, it will get better particularly after getting a new tank of fuel. But I drove it around for an hour and the gauge barely moved. The power and speed did seem to improve quite a bit the more I drove it, but still not where it should be.
The boat tops out in the low-mid 40's per the lie-o-meter on the dash, but the shop tells me that as long as WOT returns an RPM in the range of 4200-4400 that it's running fine. The boat gets to nearly 4400rpm on WOT depending on how the trim is set.
I looked long and hard for a V6 boat in immaculate condition (like this one) because I want to be able to slalom ski behind it. But based on what I see so far my arms will not be able to tolerate being dragged in the water long enough for me to pop out, due to the low holeshot power of the boat.
What should I do? Should I add a fuel additive to this tank of fuel, and try to burn it off? It's going to take me an entire day based on how slowly it's burning fuel.
It does really purr like a kitten once it reaches whatever speed, and maintains it nicely. No missing, hesistation, etc.
