If you are not having the problem with the Yamaha, maybe it was the Bigfoot prop.
I also have a Mac 19, and a 26M here in Wisconsin.

I have a Merc 50HP non-bigfoot with 12" prop - and I have the same problem.

Just to be on the safe side, I have not even tried to test whether or not the Yamaha would cause the same problem. It took a bit of effort to repair the rudder when it happened with the Merc. I just make a point to keep the engine headed straight ahead when it is running and I am moving the rudders from up to down and vice versa. Since I think we all raise the engines out of the water when we are sailing, even if still hooked to steering, there is no interference in that mode between prop and rudders.

Re: Converting Mac X to trawler
I have a Mac 19 (Evinrude 30 HP), 26C(S), 26M (Mercury 50 HP [not a Bigfoot]), and Tattoo 26 (Evinrude 60 HP) at my shop, among/amid other boats.
With the OBM(s) down, centered, cranked all the way to port and/or starboard, none of the prop(s) hit any of the rudders regardless if they are down vertically, horizontally, nor in any other position.
My 26X (Suzuki 50 HP) is in Florida. I'll be going down there O/A November 15, for the first time, this fall/winter. To the best of my recollection, my prop did not hit the rudder(s) on this boat either, but I will check.
I don't think it makes any more sense to raise the OBM out of the water when sailing than it does to dis-connect the brakes on your car when you are on the highway just because you are not using them at the time. It makes the boat more maneuverable, acting as a third rudder. It doesn't reduce the speed. If you need the OBM right now, it's one less thing to do (lowering the OBM). I was rounding a point last winter on my way to Cabbage Key for a cheeseburger when a very large powerboat came around from the other side at a high rate of speed and knocked my bow in towards the mangroves. I simply turned the key, started my OBM, put it in reverse and backed off.
I saw something yesterday that I don't recall seeing before: a pick-em-up truck with a snow-plow on the front, towing a boat.

We converted our Mac X to a trawler . We seldom used our sails , but I always kept a rudder in the water . Due to the extra weight of our boat , being a live aboard , the motor alone (50hp Honda) just never seem to have enough assss to control the boat , but with the addition of a rudder greatly improved the steering .
When in a tight spot , such as parallel docking , or strong winds , I would even drop both rudders for even better control .
The idea of a short rudder and a normal length is a very interesting idea .

Re: Converting Mac X to trawler
Bill, with all due respect, my 50 HP Merc DOES act as a drag on my
if not lifted out of the water when I'm sailing.

Re: Converting Mac X to trawler
Last winter, Charlotte Harbor, on my 26X w/50 HP Suzuki down, starboard tack, 5.2 MPH on my GPS.
I raised the OBM, same heading, 5.2 MPH.
I lowered the OBM, same heading, 5.2 MPH.
I raised the OBM, same heading, 5.2 MPH.
I lowered the OBM, same heading, 5.2 MPH, and left it down.
If my GPS would have shown the speed to the hundreds instead of tenths, It may have shown a decline in MPH.
However, I think, personally, that any decrease in speed is more than made up in maneuverability, etc. I power-sail in light winds, as I did on my way to Cayo Costa, going faster than a much larger boat with a lot more sail up.

Re: Converting Mac X to trawler
I have
with 60hp etech and prop definitely does not hit the rudders regardless of where the OB or rudders are positioned. Believe me if it could be stuffed up I would have done it at some stage.
I have left the transom ladder down and the prop definitely hits it when turning to starboard - yes I have dozens this several times

Re: Converting Mac X to trawler
Hi Bill
When you are sailing with motor down, do you disconnect it from the steering?
If not, the steering wheel is turning very hard, and all the steering is going to be stressed more.
If you keep motor down when sailing and disconnected steering, you have problems to steer, becouse the rudders are not so much effectiv any more.
I agree that the drag is not so much a problem if you are not in a race...

Re: Converting Mac X to trawler
I actually like the resistance the engine adds to the steerimg. It seems to make the wheel more stable when I take my hands off to adjust something.

Re: Converting Mac X to trawler
Bill, depends on point of sail, Beating (motor Up), reach motor down and downwind. This assumes 12 knots of winds or more. (over 18 knots motor down beating)
In winds below 10 knots and degree of wind position is much more progmento.
Lighter winds the motor is always up and centerboard most of the way up.
All depends on the condition you are in.
Powering with one rudder down or two rudders down is hardly a notice in speed, this includes running against a 2.5 knot current.
I usually power with one rudder down as I often are in shoal waters and reather chip one rudder.

Re: Converting Mac X to trawler
Really, Unless you view yourself a Woldcup class sailor regardless the boat your on... theres nothing I've found aboard a Mac that would make it worthwhile to raise the motor when sailing. I've done the GPS check also and there was no noticeable difference in speed up or down.

Re: Converting Mac X to trawler
I agree with the points above. That's what I got, too, when I experimented with the engine out of the water, The drag is minimal.
Steering feels different with the engine up. Not sure I like it better, so I keep it down at all times.

Re: Converting Mac X to trawler
Tomfoolery wrote:Several folks who've converted to a trawler have added a stub mast to replace the original, using the original hinged mast step. Add a masthead (steaming) light, which could be taken from the real mast since you won't be using it anyway, and put a VHF antenna on it, too, assuming you have a marine radio down below. You can stick an LED all-round white anchor light on the top.
I'm working on the layout of such a mast that can also support the middle of the sailing mast when in travel configuration, with the crutch jacked up 12" for clearance, and with hooks for bicycle support so they're not on the deck. I hope to make a wooden version to try, then replace with Starboard or similar after it's tuned to perfection.![]()
Poke around here for folks who've done this or similar.
I just installed our utilities mast in the step , yesterday .
Ours is made of wood and finished in wood grain . About 4 feet tall , We put the flag pole mount and all around white light on top . The ships bell is mounted a little bit lower .

Re: Converting Mac X to trawler
Another trawler question ,,,,
Originally , I said once we remove the mast , I wasn't going to fill the water ballast tank , ever again .
But after giving it some thought , perhaps safety wise it would be a good idea to run with it full .
I plan to cruise at hull speed so planning will never be anything we do .
With that weight in the bottom , the boat is more likely to be more stable in bad seas and wind .
Whats everyone else think ? How do other Mac Trawler owners plan to cruise ?
Wish we had our own smilie/avatar ,,

Re: Converting Mac X to trawler
I also added an electric motor mount in between the starboard rudder and the motor . A 28lb thrust motor fits nicely on it , but I plan to get a 55lb thrust sea water motor to go on it .
This will be more for emergencies than anything , a "get home" motor . We are solar powered , 200 watts of cells and 4 batteries , we could just about run forever on this motor.
The mount is made from an 1/4 " thick aluminum angle 8" to a side . I cut a piece of angle to go under the deck and be a faceplate to the mount . In other words I am thru bolted thru motor mount , deck and underneath plate.
It would probably hold a small hp gas motor , but I prefer electric .
