Question:

Do I have a lower unit problem on my outboard?

I just installed a ss prop on my Merc 70 hpNow when I shift into gear, either forward or reverse It makes a bad rumbling noise at idle speed around 700 rpmWhen I speed up to around 1200 rpm it stops and everything is greatShifts fineNew thrust washer installed.Checked gear lube and no metalDidn't do this with aluminum propI know the ss is much heavierCould the extra weight be the problem?

Answer:

Yes the pan it comes in is to be used to cook it inYou could also remove the frozen lasagna and place it in your own pan and bake it in thatIf you want a fancier presentation and you have a pan that you want to use then just pop the frozen lasagna out and put it in the pan you want to use.
Yes, of course you do; that's why they put them in the pansJust follow the directions on the box.
Yes you doAll you have to do is read the directions! Leave the top on and bake for how ever many hours the box says.
I've seen this issue come up many times on many boats we take care ofIt turns out, that with the weight of the propeller that the motor has to spin, and with the tempermental idle of a two-stroke outboard, that the shaft that runs from the bottom of the motor itself down to the propshaft is actually being jerked back and forth against the splines on the bottom of the motor (coupler) and usually, if your propeller is installed correctly, that is the caseI personally have never seen a stainless propeller on any motor smaller than a four stroke 90 HP Mercury or Yamaha, and most of the time Yamaha's come with aluminum propellersThe factories for all marine engine manufacturers send out different props for each motor, and not most of the time, but ALL the time, they send the engine/drive packages with the prop that performs the best in all situationsMy recommendation to you would be to put an aluminum prop back on this motor and call it goodIf it was a 225 HP Mercury w/ that rumble I wouldn't worry about it because a stainless prop comes with that motor from the factory (and the 225's, before the OptiMax did rumble)Happy boating!
Yes, you leave it in the aluminum trayYou will need to take off the cover (and ALL paper and plastic!!) and tent the cover so when you put it back on it won't touch the lasagnaSet the timer for about 15 minutes short of the full cooking time so you can take off the cover and brown the lasagnaAlso, make sure that after it's cooked, you take it out and let it stand 15-20 minutes so it sets up (gets more firm) - or you will end up with lasagna soupEnjoy!
