as above!I'm 16 and I want to buy a boat?
The choice of short, long or extra long shaft outboard motors depends on the size and type of your boat. You must measure your transom in order to determine what shaft length motor you need. Keep in mind that the cavitation plate should be flush with the bottom of the boat. You can get away with an inch or two either way but it is wise to keep it close. If you are still unsure of what kind of shaft you need contact your boat manufacturer or look them up on the Internet.Where is the identification number on the Reo pick-ups 650 and 450?
Its the vertical distance of the prop from the mounting. This distance varies with the size of engine and for the requirements of the boatWhat do I need to sell my Jet ski?
good grief!! measure the back/transom of your boat from top to bottom. if it's close to 15" then it's a short, if it's close to 20" it's a long. choose the motor that fits.about 5 inches.
I'm trying to find a power tilt & trim unit for a 1986 johnson 40hp outboard motor, in New Zealand?
its basically the length from the bottom of the engine where the engine transome clamps onto the boat,to the propeller.if the boat sits high in the water long shaft,low in the water short shaft.For long shaft obm were designed to fit on high transom boat usually measured from lowest point at the bottom of the transom to the top where the obm clamp sit , about 21" in.for yamaha & 20" in. for mercury ( sorry ,for other brand you may refer to the respective manufacturer specs because I never had one).As for short shaft it were designed to fit on lower transom boat which usually measured from top to bottom around 15" to 15½".There were XL & XXL found on high power motor which fit to 25" & 30" transom respectively to cater high transom boat usually installed with 2 or more big & heavy Obm thus the load won't sank the stern as the load may excess ½ tons or more depend on engine sizes & quantity.The transom heights recommended by obm manufacturer shall be followed in order to achieve optimum performance and reliablelity of the motor as.Lonn shaft Obm has longer ``leg'' compare to the shorter shaft by 5"in. in length measure from clamp gape to the top of cavitation plate.This will allow the props and cooling water pick up were ideally submerged in the water.Long shaft obm if installed to low transom boat may compromise the handling as to turn the the boat become difficult task with tiller model and water will be drawn from the back when move due to deflection on the obm lower casing.
What kind of truck would you recommend to pull a 1400 lb boat on a trailer?
It is simply the length of the 'leg' inside which is the drive shaft from the engine, up top, to the gearbox in front of the propellor, down below.It's just a matter of what is suitable for different installations. Most small, outboard-driven boats take short shaft engines because that is what they are designed for. On auxiliary yachts by contrast, with their comparatively tall transoms, longer shafts are often needed - or else, by the time the propellor was in the water, the engine would be so far down the back of the boat it would be impossible to get to, to start and control!
