New Motor To Do's

[PaulKim]

I am going to be purchasing a new 90ELPTO. <br /><br />What things should be done when I am installing the motor?<br /><br />For example, fill lower unit with oil, fill tilt/trim with oil.<br /><br />Will I need to monkey around with the spark stop, or do they come pre-adjusted from the factory?<br /><br />Any advice you have would be much appreciated.<br /><br />Thanks<br />Paul

First thing to do it read the owner's manual. <br /><br />New motors come with gearlube and tilt fluid. Check the gearlube, it's usually a tad low. Also check the trim fluid with the motor fully up. They're usually a bit overfull which is okay. You'll want to add some 2-stroke oil to the oil tank too. Premix a full tank of fresh regular unleaded gas at 50:1 for break-in.<br /><br />Read your owner's manual. <br /><br />For average use, mount with the antiventialtion plate even with the bottom of the hull. One hole higher for a bit more speed, one hole down for more bite if you frequent rough seas.<br /><br />Read your owners manual. <br /><br />The rigger is supposed to double-check timing and synchronization as they only ballpark it at the factory. I find they're pretty accurate with their ballparking. If you're not familiar with how to do it, it's probably best left alone.<br /><br />Read your owner's manual. <br /><br />Don't use regular Silicone to seal the holes, but Ultra Silicones work wonderfully. Seal the motor against the transom and the washers inside the transom. Bolt heads inside the transom on top, on the motor on bottom.<br /><br />Oh yeah, read your owner's manual. Write the serial and model number inside the cover. On the inside of the back cover, write that you checked the fluids and the date. Keep track of any such maintenace and repairs. Then put it in a Ziplock IN YOUR BOAT! I rarely see owner's manuals in boats! They don't do you much good sitting at home.

I should add not to be too concerned about getting a smooth idle out of it. They shake. Adjust the shift so that it takes the same amount of lever to get both gears. Change the gearlube after awhile. There's a recommendation in your owner's manual, but I'd change it at 5 - 10 hours. Most of the wear happens early as the gears break-in. The prop from your 75 should be okay, but you might find you need to go one higher in pitch. Never hurts to have two props, one for more power and one for more speed.
