I'm about to join the four-stroke engine club
The port engine on my Grady quit running while heading back in last week.
The problem was diagnosed as a faulty low pressure fuel pump. It's a pretty inexpensive part, so I told the dealer to replace it and the five other ones as a precaution. But that same day, the owner of the dealership called to pitch me on four-strokes. With my old motors as trade, and reusing my existing gauges and binnacle, it became pretty cost effective to replace the old two-strokes. I figured that the fuel (gas and oil) savings alone should be about $3-4000/year. But more importantly, I'm going from a 5 year old motor with no warranty, to a brand new motor with a 3-year warranty. I may not keep the boat the 7 years it would take to recoup (in gas money) the additional cost of upgrading. But if something major went on the two-strokes in the next couple of years, I'm way ahead with the new engines. Also, if I sell the boat in 4 or 5 years to upgrade to a different boat, I figure it would be much more marketable with 4 or 5 year four-strokes, than 9 or 10 year old two-strokes. I'll be sure to post performance data on the engines vs. the old ones once I get past the break-in. The new engines are twin Yamaha F250 four-strokes. |

I saw a pair of those on the new Parker 28-foot pilothouse. Made me glad Yo Ho runs fine on one engine. Next year, I was told, there may be a new block Yamaha fourstroke of 300 hp. If so, and if I still have Yo Ho, I'll trade up. Email me if you will with what you figured you got in trade for the old engines. I'm pretty sure I got ripped on the old engines. I'm getting the new four-strokes installed for $28k out the door. There is some incentive money from Yamaha right now for rigging on the new engines. He's showing me about $8k in trade on the old engines, but I'm guessing that he's giving me about $4-5k in real money. The older 250 two-strokes aren't worth much money right now with fuel prices as they are. The dealer says that he plans on shipping them to a buyer "in the islands". Your F225 would be worth quite a bit more on resale, because everybody wants the four-strokes now. |

Your F225 would be worth quite a bit more on resale, because everybody wants the four-strokes now. I was quoted my F225 and $2500 for a 2006 250 hp, a bit higher than usual because "Gee, you take really good care of your stuff." I suspect if there is a 300 hp four stroke next year, I'll have to pop for $3500-$4000 and my trade. Parker, by the way, had a nice price increase in its lines. There's a used 2003 boat just like mine in the area for sale for $63,500. I love it. I've had virtually no depreciation. There are similar boats "on the market" and on the web for the high 50's, but around here, Parker and Grady rule, and they are easy resales for damned good prices if they have been maintained properly. This is definitely *not* the place to get a 'good deal' on a used Parker or Grady! -- 'Til next time, John H ****************************************** ***** Have a Spectacular Day! ***** ****************************************** |

I'm not too unhappy burning 10-11 gph at a nice cruise speed in Yo Ho. Faster than that, and I have to wield a scimitar. According to Grady-White and Yamaha... 42.6 gph at 47.5mph. http://www.gradywhite.com/popup/spec...300&file=F250T But I should be burning 4-5 gph less with these engines at 30 mph than with the old two-strokes. |

Did you consider a E-Tec instead of the 4 stroke, and what was your reasoning behind buying the simpler, less complex, but HEAVIER 4 stroke, vs. the realitively new high tech, complex but much LIGHTER E-Tec?

Harry,
Since your current engine does the job without any problems, and your current usage would never justify the expense of the new engine, why would you consider buying a new engine ? |

In the 1970's, the Honda 750 motorcycle got better mileage than the smaller 550. Terry & Skipper, Clearlake Texas Sure. And 2006 Ford F-150 will get about the same gas mileage with a V-6 or a V-8 if the trucks are both empty. Boats are a bit different but all that really matters is that Harry isn't trying to save gas money so his response to Smither's questions is yet another mystery. |

Don't worry too much joining the four stroke club.
Now that you're well into your thirties, it isn't all that unusual to require four strokes to develop the same sort of motive power that you can remember from the glory days when two strokes were sufficient. As the hull gets heavier and slower and picks up a few nicks and barnacles it is very common to require a four stroke to sustain performance. The good news is that reports from satisfied users of the four stroke models indicate a general impression that the ride is more sophisticated, refined, and somewhat smoother than the high speed two stroke units. A two stroke is just perfect if your intention is to sprint as quickly as possible to the finish line, but for a long sustained run you will discover that the four stroke has a number of advantages. Like the outboard repairman once told me: "As long as you can get it started with no more than just a few pulls, you can continue to get a lot of enjoyable service from a beat up old Johnson." |

I got the motors a few weeks ago, and was running it with 15 1/4 x 17"
props. That was too little prop for my boat (it ran the motors to 6100 rpm and 43 mph) At the 10 hour service after break-in, I repropped to 19" pitch. Performance is phenomenal. Who says that the new four-strokes don't pack the punch of the 2-strokes? Top end is between 46 and 47 mph at 5600 rpm...and that's with full eisenglass up, 3/4 fuel (1200+ lbs), generator, and 5 people plus gear. Mileage was an astonishing 1.1-1.2 mpg at WOT. The older 250 OX66's ran that boat to 43 mph, but only got about 0.7mpg at WOT. Most economical cruise speed is anywhere from 3800rpm (28mph) to 4400 rpm (34 mph)...yielding about 1.5 mpg. At trolling speed, fuel burn is half what the 2-strokes burned. And at "just-on-plane" speed (18.5-21mph), the new motors get 1.3-1.4 mpg...and the 2-stokes got 0.8 mpg. Did I also mention that I can carry on a full conversation on the cell phone while running WOT? I figure these motors will save me about $2,000/year in fuel/oil costs...which pays for the extra $140/month in my payments. When you add in the extra cost for insurance, though, I break even. Still well worth it considering the warranty, and the pleasure of no-smoke and quiet operation. "NOYB" wrote in message ink.net... The port engine on my Grady quit running while heading back in last week. The problem was diagnosed as a faulty low pressure fuel pump. It's a pretty inexpensive part, so I told the dealer to replace it and the five other ones as a precaution. But that same day, the owner of the dealership called to pitch me on four-strokes. With my old motors as trade, and reusing my existing gauges and binnacle, it became pretty cost effective to replace the old two-strokes. I figured that the fuel (gas and oil) savings alone should be about $3-4000/year. But more importantly, I'm going from a 5 year old motor with no warranty, to a brand new motor with a 3-year warranty. I may not keep the boat the 7 years it would take to recoup (in gas money) the additional cost of upgrading. But if something major went on the two-strokes in the next couple of years, I'm way ahead with the new engines. Also, if I sell the boat in 4 or 5 years to upgrade to a different boat, I figure it would be much more marketable with 4 or 5 year four-strokes, than 9 or 10 year old two-strokes. I'll be sure to post performance data on the engines vs. the old ones once I get past the break-in. The new engines are twin Yamaha F250 four-strokes. |
