I think it will be a great combo as long as you can handle a top end of 28-30mph which is about where my old 25 Johnson pushed me. The weight should be fine, my 13 sat real high in the stern due to the 25 manual start with no battery, etc. |

We just had a similer discussion comparing the Yam 30 v. the Honda 40. The Honda 30 only weighs 138lbs and would meet and exceed your performance criteria. Consider going to Canada to save 30% or more! |

I put a 25hp 4 stroke Merc Bigfoot on my 13 last year. It tops out at about 28. Gets out of the hole in a hurry, and is great at slow speeds. No weight problems at fast/slow or reverse speeds. Perfect for the 1100 acre lake I live on, and keep it on a boat lift. |

I'd be real interested in opinions of any others that power their Whalers with 25 Big Foot. Can it plane with 4 adults? I don't care about top speed more than reasonable transom weight and low end power? Thanks. |

I don't know about the 4 stroke, but my old 13 would plane 4 adults with a '96 Merc 2 stroke (Average weight about 165#). It would not, however, jump out of the hole. |

My catolog says that the yamaha is 139 lbs for the 4 stroke 25, but then it says that the high thrust 25 is 190 lbs. IS that a misprint? Also My friends are repowering a MINT 1969 whaler that has a 1980 25 evinrude 2 stroke. I am recommending the 25 yahama 4 stoke, they have the orginal cable steering on the boat and need to know if they can get an adapter to use the new 2003 25 four stroke to use the cable steering, or should they just upgrade to the teleflex. I want them to keep the boat as orginal as possible. I have tried to buy this boat for years, but they wont sell. |

Should be an EASY way to connect. Just bolt the old adapter that connected it to the front of the OMC to the steering arm. If clearences are Ok and she tilts fine, use it. If not anything would work just to bolt it to that arm. |

Regarding new engines,the 2003 25hp Yamaha electric start, remote control 4stroke seems to be the only 25hp(2 or 4 stroke) that has trim/tilt(optional), and the weight(about 136lbs) seems reasonable for a 13. The price here for that engine in a box with side controls is $3500 which is a problem. Do you all have any knowledge of better prices, please? Whom to contact in Canada too? Thanks, Lew |

I have seen 25 Yamahas for $2400 w/o PTnT so i would think $2900 would be about right. Look on e-bay and start shopping, plenty of places in FL to get a cheap engine. |

The Tohatsu/Nissan 40 hp is available with tilt/trim and oil injection (integral oil tank) in the short shaft (15") version required for the older 13s. It's 3 cylinder motor at 158 lbs and sounds like the perfect mate for a classic 13. They also make a 30 hp 4-stroke that weighs 150 lbs. |

I would do the 30 4 stroke Tohatsu if you can get a better deal. Tohatsu makes Mercurys smaller engines, not sure who makes the Merc 30 4 stroke, might be tohatsu. |
