Please use this discussion exclusively for comments and questions about the article in the REFERENCE section by Robert Schmidt on Sea Drive Conversion There are many older Boston Whaler boas with Sea Drive OMC engines available from time to time, and they represent a very good way to get into a full transom Boston Whaler. Robert and Brian did an excellent job accomplishing the conversion, and Robert did an equally fine job on documenting and photographing the process, as well as writing the article. It is a great pleasure to add this to the REFERENCE section. I think it will be a very popular addition. |

Rob was very gracious and shared this article with me some time back. My son and I are tackling the same project on our 18 and being able to go to school on Rob's presentation has already been extremely helpful. Thanks again Rob. |

No problem, I hope it helps anyone else thinking of taking on this project! |

I had a early 80’s 22’ Robalo with a V6 Sea Drive. All I can say about the Sea Drive is to quote Donald Sutherland from the Space Cowboys movie “What a hunk of junk”. The way OMC built the huge brackets and so on should have been relegated to commercial barges only. The rig was wayyyyyy too heavy and detuned for consumer applications. I replaced ( the work was done at Moriches Boat and Motor in E. Moriches, NY) the 140-150hp V6 Sea Drive with a 225hp V6 Suzuki. The Sea Drive brackets were replaced with a positive flotation Armstrong bracket. The hydraulic steering was upgraded to SeaStar. With the extra hp, lost weight and 30% better fuel mileage- the old Robalo seemed like a new boat. I’m sure Mr. Schmidt feels the same way about his “new” Outrage too. |

Rob's article shows that for those with the time, motivation and talent, there are some excellent full transom Whalers out there just waiting for a new lease on life. I often see SeaDrive Whalers languishing on the market, and I suspect many of them can be had for below market prices as compared to notched transom models. Nice work Rob! |

I continue to be amazed by the quality of work that I see on this site, both amateur and professional. Big transom holes just disappear, chewed up chines reappear as good as new, entire decks get replaced without a trace of rework. It's astonishing how well these boats can be brought back to like-new condition! |

I have an '87 22 Revenge WT that had twin seadrives. We did a conversion about 3 years ago to an Armstrong bracket and a single 225hp outboard. We did a little ourselves but most was done by a marina. When I have time I will put together the story on it. It is now a very nice rig, with great performance, that sought after full transom and a much more fuel efficent setup. Boat is on Lake Michigan in Chicago and may be for sale in the next year or so.

Thanks for the post. I never considered a jack plate and had always assumed that I'd have to put a heavy bracket on the back of this one when the time comes... http://i15.photobucket.com/albums/a360/CUOffshore/18Whaler1.jpg http://i15.photobucket.com/albums/a360/CUOffshore/18Whaler3.jpg Now I am thinking a jack plate and a 200 Yamaha (or an E-Tec) would be perfect! Thanks again. -Dave |

Dave, that's a beautiful Outrage. Considering all the extra laminate and plywood that was added to the Outrage-18 with Sea Drive, I think 200HP should be nooooo problem! |

Can you explain me : Was the 18' originally with a standard transom and an outboard engine or was it originally with a full transom using a sea drive. Thanks in advance. |

You don't need to modify the transom to install a bracket. See here: http://continuouswave.com/whaler/cetacea/cetaceaPage45.html David |

The entire process of the modification is shown in the REFERENCE article linked above. The boat was built at the factory with the full transom and the Sea Drive power. This was an option which was available for a few years. You can learn more about this option in another article in the REFERENCE section on the general topic of set back brackets.

That does it! I am going to paint my SeaDrives metallic blue, and put Yamaha decals on them. |
