Also,

With the new outboard the boat has a noticeable lean to port side. Seems like the heavy weight on of the engine is causing the lean.

I have the water tank on the opposite side of the engine located under the settee. I have never filled it but am know considering filling it to add some weight to the starboard size to balance out the lean.

Will this work??

Anybody else have a similar problem with these larger engines?

Thanks

What motor did you buy? I replaced an old 88lb 2-stroke Suzuki with a new 93lb 4-stroke Nissan, so no noticeable change.

Odd that the Mercury would be so much heavier, since it and the Nissan are both made by Tohatsu. - Okay, just looked at the pics. Your got the Big foot model. I looked at that one, too, but decided against it due to the extra weight. Great looking boat, by the way!

For what its worth catalina drawings show the outboard to be on the starboard side-my 80 cat had a port list and I queried Catalina and rcvd the drawing.

Filling the water tank should help--it's further off the centerline than the outboard, so the up-to-160 lbs. will easily offset the extra poundage of the Merc. If not, you were probably listing before.

What's the difference in the Big Foot model and the regular? I was looking at possibly buying one of these but couldn't find anything that noted the differences.

The water tank, assuming it's standard holds 18 gallons of water, so that's 144 lbs. I was reinstalling my fresh water system on Saturday, so I got a pretty good feel for the empty weight of the tank, it's may 10-15 lbs. So call it a ballpark figure of 155-160 lbs full. I would do as Dave suggested; fill it up and see if it makes the boat sit level.

>Will this work?? [filling the water tank]

Yes. Also relocate other heavy items to the starboard side as needed.

>Anybody else have a similar problem with these larger engines?

Yes. 125 lbs hung off the transom is going to have an impact on trim.

Any listing will be unnoticeable once your sailing and the boats heeling takes over.

Stuart;
does your 1980 have a fuel locker in the cockpit or in the lazerette? Either way, it is probably on the port side along with the motor, so that is adding 42 lbs. if you have a 6 gallon tank. My '82 has a fuel locker in the cockpit, but my motor is mounted on the starboard side. I have an old 15 hp, 2 stroke Merc. but I don't think it is as heavy as yours. I don't have any perceptible lean on by boat. For everyone's information, the hull thickness on the Starboard side of my year boat is over an inch thick, because of the hull thickness, plus the thickness of the hull liner in the quarter berth, plus what appears to be foam core in between them, so no backing plate seems to be required on that side (at least not a steel one). I added a quick disconnect plug for my electric start this spring, and cut a hole through the hull near the stb. side motor mount with a hole saw, and measured the plug thickness I removed. The port side of my boat is just the hull by itself, and only about 3/8ths inch. so a hefty backing plate would be required if mine were mounted on the port side.

I have a Chrysler (10hp) mounted on the port side with the locker for fuel (1978) on the port side as well. My boat leans to the port side especially when I have a 6 gallon tank full. The water tank is on the starboard side, so it logical to think that water on the starboard side would help center the boat.

Perhaps it may be easier to have all my passengers sit on the starboard side, heh.

BIG FOOT: 1. larger bearings, bushings, gears, and shafts in the lower unit
2. 2.42 gear ratio instead of 2.06 (better for displacement hulls)
3. 4 blade larger prop for more thrust at low speeds
4. much heavier
5. significantly more expensive

I opted for the standard Merc in my recent purchase, but the Big Foot would be sweet on a larger boat or in a lighter 8 HP version. Incidentally, after ordering my Merc last week, I looked at Practical Sailor's last review of 9.9's. Surprise - Mercury got the star. But, as many of us have said on this forum, both Tohatsu and Honda got "recommended" ratings because the differences were so minor.

Launched my 80 cat25 TR yesterday after changing the outboard from port to starboard side-very nice to be on an even keel(NO PORT LIST)
