J.B.,<br />You helped me before with a prop question. Now I need to know what to do to prepare my 1997 18 Ft. Caravelle, mid-console and 1997 120hp Force for saltwater use. Have used the boat only in freshwater and plan to take it to the Keys (intercostal waterways) over Christmas. Any suggestions for preparation and what to do after taking out of the saltwater.<br /><br />Thanks in advance for any help you can provide. :)<br /><br />Mike

I live 140miles north of the Keys on the west coast. What we do here, is go where we want to (OBSERVING THE IDIOTIC MANATEE IDLE ZONES), and then flushing the motor just as soon as possable afterward. Some ramps will have a hose,most will not, so before even putting-in, find the hose at your hotel, and make sure you will be able and allowed to use it asap when you get home.<br />Before unpacking the boat, hook her up,and run on the muffs for at least 5 minutes. When you are done with the engine, take the hose and wash-down the trailer inside and out.What I mean is, get inside the channel steel,under the axle,and everywhere else.<br />I use a local coin car wash for this,as it does a much better job on both boat and trailer....But the motor gets flushed first.<br />Lastly, grease the hubs. This is also vital.If you don't have a grease gun, buy one, allong with a roll of shop towels.The small hand-held guns with 3oz cartrages are ideal. They are cheap,small,capable, and can be stowed onboard,or in the trunk of your tow vehicle.<br />It would be best to get one before you leave, and give each bearing a shot when you get fuel on the way down. Trailer wheels are small,so they turn much faster than auto wheels. The bearings require constant attention to keep your rig off the side of the road.<br />I'm just telling you all this in case you didn't know allready...I want you to enjoy your trip :) to the max.<br />If your trailer hubs are not equipped with bearing buddies (a spring-loaded grease retainer) on the hubs, look-into purchasing and installing them before the long tow.<br />You won't be sorry.

I also recommend coating the exterior of the engine and prop with WD-40 or wiping it down with some oil on a rag. I actually spray all the exterior bolts and drain plug also.<br /><br />I live on the Chesapeake Bay and saltwater is an enemy, but proper care of you motor will prolong its life.<br /><br />Also, "YES" don't forget about the trailer.<br /><br />One other tip, >>> DON'T forget to spray the underside of your car down. Your car wheels have bearing too....

p.s it is only neccessary to clean the underside of the car if you TOTALLY emmerge your car in the water! :rolleyes:

Also (just a personal mishap here) service your wheel bearings BEFORE (and after) the trip.... I mean pull 'em, clean 'em, and greese 'em. (also carry a spare wheel bearing, hammer and chisle...) If you have it hopefully you won't need them (ps it is impossiable to find a trailer wheel bearing at 5 o'clock in a strange town on a Sunday.... Been there done that...still kick myself) Also carry a spare tire.. And have a blast....

Seaboo sure has been there. I have a spare tire mounted to the trailer of my boats.One<br />weekend,I decided to head for the "Big-O",and do a little bass fishin. I loaded the gear,checked the hitch,motor (everything you would check before a 60mile tow)---EXCEPT the spare tire pressure. It turned-out to be flat,and I had one in LaBelle. It took me 3 hours to get on the road again. Frustrated,I turned around and went home.

Thanks 12footer, fishthebay, oldseadog, and seaboo for all the good information. We will check out the trailer bearings and the trailer spare tire pressure. We will take a hose and the muffs with us for sure. We are planning for a great trip and appreciate your advice. <br /><br />Mike :)

I'm not sure if the Force has a sacrificial zinc on the lower unit. If not, I'd buy a small tear drop zinc and mount it on top of the cavitation place. You'll have to drill 2 holes in the plate edge just like you'd do for a hydrofoil. Even though you're only trailering it, I'd still put the zinc in because once galvanic corrosion starts, it doesn't stop; it just slows down. Then a year from now when you're changing thermostat bolts and one snaps, it won't be overtorqueing, it'l be galvanic corrosion.

msurma,<br />One last thing regarding towing, which would seem like common sense to most, is to stop periodically and check the temperature of the rear trailer hubs. On a long drive, they should be warm to the touch but not hot. If they are hot, you're baking the bearings and you'll probably have a failure in the near future. <br />Nav :)
