A bunch of newbie outboard questions

I just bought a boat and it has an early 80's 9.9 tiller Evinrude. I have a couple of probably obvious questions, so I'll just list them all here as opposed to different threads for each.

It seems to run ok, and is quiet when the motor is idling in a trashcan filled with water. However, the exhaust is really loud using "muffs". It seems as if the exhaust comes through the propeller. Is this correct? Is that where most exhaust goes?

After idling it for a long time in water, I removed the trashcan and what can only be described as "wet mud" seemed to be oozing from the exhaust area in the center of the prop. It had an exhaust / fuel / oil smell. Is this normal?

I'll be using this boat in the winter. As opposed to winterizing it, what would be the proper method for protecting it over a few days to a couple weeks without use in freezing temps after it was just in the water? I've been told to run it for a couple seconds after pulling it out of the water to get water out of the system. Taking it off and hauling it inside doesn't seem like a good option everyday.

The boat runs smooth on "start" with the carb adjusted where it is. It needs to be leaned out some to run smooth on "slow". But if I lean it out, it won't run smooth on "start". Is this discrepancy a sign that I need to rebuild the carb? The previous owner said he "cleaned the jets" but was honest that it may need a carb kit. I want it to run smooth in all power ranges.

Related to the previous question, the engine has an idle speed adjustment on the side. Should I try messing with that as well?

For electric start engines, does anyone suggest buying one of those on-board chargers and just mounting it inside the boat? recommendations?

It was suggested to me and I currently have sea foam added to the fuel. Any concerns with this? How often should I add it to my tank?

I'm looking for a larger motor as well and I see a number of non-tiller models. I know there are tiller kits for most engines, but they are $$$. Is there anyway to DIY a tiller or could I put controls for throttle back where I sit on the back and just steer with a DIY tiller handle? I see tons of old motors going for cheap, but none are tillers.

Yes, exhaust does come through the prop on those models.

That is normal. It is just unburnt fuel mix from the engine.

Under no circumstances do you ever run it out of the water. It only takes 5 - 10 seconds to roast an impeller, running it out of the water. If you take it out of the water, just make sure all the pee holes on the lower unit are clear, so all the water will drain out. You might turn the flywheel slowly with the hand starter just to get all the water that may be trapped inside the water pump. Laying the motor on its back afterwards is also a good way to drain out the last bit of water.

It is normal to lean the jet a little bit, once the motor gets warmed up. If it runs good, I can't see a need to rebuild the carb.

Related to the previous question, the engine has an idle speed adjustment on the side. Should I try messing with that as well?

That is just a throttle stop adjustment. By adjusting that, it allows your motor to stop at your desired idle speed. Since your motor does have a push button kill switch, it is okay to set your idle up a bit, for a desired trolling speed.

For electric start engines, does anyone suggest buying one of those on-board chargers and just mounting it inside the boat? recommendations?

These models do come available with electric start. Typically, the battery will hold a charge long enough to last you through the day fishing, without having a need for a charging system. Even if the battery does go dead, that motor should start after the first pull, if it's in good running order.

I'm looking for a larger motor as well and I see a number of non-tiller models. I know there are tiller kits for most engines, but they are $$$. Is there anyway to DIY a tiller or could I put controls for throttle back where I sit on the back and just steer with a DIY tiller handle?

Yes, there are tiller handle kits available for motors that are over 200hp. Most people with larger motors will typically use remote controls with theirs though. If you are mechanically inclined, it may be easy enough for you to convert one to a tiller handle set up. How big of a motor are looking to purchase? Motors under 50hp are a lot simpler to find second hand tiller setups at various salvage yards. Here is a list, for your future reference.

Re: A bunch of newbie outboard questions

Thanks for the info.

I'll be using this boat in the winter. As opposed to winterizing it, what would be the proper method for protecting it over a few days to a couple weeks without use in freezing temps after it was just in the water? I've been told to run it for a couple seconds after pulling it out of the water to get water out of the system. Taking it off and hauling it inside doesn't seem like a good option everyday.

If you take it out of the water, just make sure all the pee holes on the lower unit are clear, so all the water will drain out. You might turn the flywheel slowly with the hand starter just to get all the water that may be trapped inside the water pump. Laying the motor on its back afterwards is also a good way to drain out the last bit of water.

So taking it to the river, and just pulling it out and allowing it to drain for a minute in the vertical position should keep it from freeze damage if I don't take it out for a few days and its 15 degrees outside? Would turning it over with the starter but not starting hurt it?

Yes, I'm looking for a 25-40 HP. The boat is rated for 50.

Well, I would just turn the flywheel with your hand a couple revs so it doesn't risk starting the engine. Turn it clockwise only though, so you don't reverse the veins on your waterpump. That is all you would need to do, to get any water trapped in your impeller.

You should easily be able to find a tiller handle kit for your motor.

Re: A bunch of newbie outboard questions

it's very important to do as 1946Zephyr said and make sure that the drain holes are clear so that water doesn't get trapped, freeze, expand and break things.
