I am planning to replace the 6 hp '79 Johnson outboard on my Oday 19, with a newer 8 hp Yamaha, Honda, or Merc because I need greater reliability and power. The 8's weigh 25 lbs more, around 83 pounds (my 6hp is 58 lbs). It has been suggested that a newer 6hp might provide all the power I need at similar weight (61lbs) , but I would like to go with an 8. My questions 1) Can that Oday motor mount (pictured below) handle 80 pounds 2) I don't see how to gain access to inside of transom where bolts/nuts fasten motor mount bracket assembly to hull (one of the 4 bolts/nuts may be slightly loose) so that I can ensure all are tight. Thanks, Bill
Oday 19 Motor Mount Capacity and Access

I would question whether that mount could handle an 80 lb motor, or whether you need that big of a motor. When I had my O'Day 222, I repowered with the 6 hp Tohatsu 4-stroke. It weighed around 50 lbs and easily pushed the boat at hull speed, even in some Lake Michigan chop. I did replace the motor mount and wedge with a heavier duty Garelick mount. I also added a powerthruster to improve fuel efficiency, as well as avoid dinging the rudder with the prop, and prevent the motor from turning unexpectedly in heavy waves and cavitating. It worked great. (See one of my photo albums for details: http://forums.oday.sailboatowners.com/album.php?albumid=2157) . Note that I removed the wedge (not needed because the new mount could be set at different angles) and reinforced the backing plate when I changed the motor mount. I would suggest you think of alternatives to such a heavy motor on the transom of a 19. That is too much weight in my opinion and not needed to push the boat.

Thanks Dave. Others feel the same way and I think I'm moving back to a 6 ... a much newer 6hp adjusted to drive the 19 thru the heavy winds and chop of Lake George. I'm not sure I understand how you avoid dinging the rudder with the prop. My rudder is pretty heavily 'dinged' from previous owners and I would like to fix and prevent that. Thanks for the link, I will now take a look at your album.
I'd stick with the 6 HP on that boat. I used to think that four stroke outboards should require an engine bracket rated for a four stroke and I've since adjusted my thinking on that. I think that you can get away with a regular bracket that is rated for the weight of the engine. If anything, I would make sure that your transom is beefed up enough on the inside.
If you feel that you want to change the engine bracket to a more heavy duty bracket, I would install an 8" Beckson Deck Plate in the center of the inside transom to gain access to the nuts and backup plates of almost every piece of hardware on your transom.
One of my friends gave me a fairly new Panther outboard engine bracket last year and I was able to remove my old Fulton Bracket and mount the Panther in it's place. I didn't have to disturb the fiber block on the transom and the bolts holes lined up beautiful. I couldn't have done it without that deck plate.

An 8" plate would be a huge improvement vs the 4" circular plate which you can't get your arm thru with any reach. Thanks for suggestion. I will be able to reach nuts on bolts holding current bracket and will have better access to cockpit drain tube which had been source of a leak into hull reported earlier. I was just surprised that Oday wouldn't have provided access to major bolts holding motor bracket, and thought there might be a trick for getting in there e.g. thru seat locker on starboard side ... where access is blocked by floatation which seems afixed to hull. Thanks again Joe.

Bill,
When you install the deck plate it may not lay flat on the curved surface of your transom. It's important that you don't over tighten the screws of the flange which can bend the flange and cause the cover to bind when you screw it on.
I would use a good silicone caulking like "Dap Silicone Rubber Adhesive Caulking" which can be bought at any hardware store. Any small gaps between the flange and the transom surface will be filled by the caulking and it should come out looking pretty decent.
I used that stuff this past spring to adhere a lexan lens to my forward hatch and it sticks better than anything I've tried. I would recommend it for any plastics including hatches and port lights on the side of the cabin. The surfaces need to be cleaned well with denatured alcohol in order for the stuff to stick. I also roughed the surfaces with my Dremel Tool sanding drum.
The powerthruster is sold through this site and just attaches to the cavitation plate on the lower unit of the outboard.

It worked well for me, and no more dings from the prop.

Thanks Joe. A bunch of important points and valuable tips in there which I will follow. Nice to know what to expect before starting a job. Bill
Your photo album was great and answered many of my questions. Now I know where to get one of these powerthrusters. I can't believe I've had a camp on Lake George my whole life and been around a lot of boats and motors (although more sail than motor boats) and never heard of or seen one of these ... which seems to make a lot of sense. So Thanks for the Link, Dave.
Bill,
My views on engine brackets are of my own opinion based on what I've seen and heard. I've talked to Rudy Nickerson at his store and he showed me a heavy duty outboard engine bracket that is built like the Garelec bracket, yet it is not rated for a four stroke engine but some guys with O'Day 25s in the area have been buying his brackets and mounting four stroke engines on them as large a 15 hp. They haven't had a problem with these brackets.
My friend Wayne has a similar bracket on his Seaward 22 with a Tohatsu four stroke 9.4 Hp mounted on it. He was more concerned with his transom thickness so he beefed it up with stainless steel plates.
I also think that the power thruster is the way to go. I've had my prop hit my tip up rudder blade more than once and had to make repairs to my blade. That can get old fast.
