How To Mount An Outboard Motor Properly - Start to Finish!

[Music] hello everybody welcome to technicians Tuesday today we will be going over the process of correctly mounting an outboard engine at the right height and how to measure and set up the tie bars we'll go into some other parts of the process as well so let's get into it for this video we will be removing three 300 horsepower Mercury Verado x' and installing three 350 horsepower barratto's this is a 34-foot yellowfin and we will get started by derating the engines for these virata's we just disconnect the fourteen pin harness here push in this red tab and pull off the fuel line disconnecting the can network cable the power steering wire fuel sensor and then power cables now with the rigging out we need to remove the tie bar and then we can take off the steering cylinder hoses this boat has a large starboard platform built where a cooler can sit we have to remove that and pull up the access plates so that we can get to the mounting bolts for the engines then with the engines ready for pulling we set up some tires where we could lay the old engines and now we can install the lifting eye onto the engine and get it hooked up to pull them off pulling the engines is pretty basic once we get to this point we take out the four mounting bolts and work the engine off of the transom this can get difficult because of the sealant that is behind the engine so we just worked the engine back and forth until it releases and comes off [Music] [Music] [Music] with the engines off it's usually the best time to clean off the transom change out the rigging tubes and get everything set and ready for the new engines [Music] I like to drill out the old 5200 from the bolt holes so that the new bolts will slide in without giving us a huge hassle we'll uncrate the new engines and carefully remove the cowling so that we can install a lifting eye then lift the engine all the way up and set it back down onto the crate so we can remove the crate [Music] [Music] for these engines once the crate is removed we moved the steering cylinder from the center motor over to the port engine this saves us some time in the rigging Department before putting on any sealant you want to get the engine up and against the transom so that we can set the engine height there are a lot of rule of thumbs out there some say one inch lifts for every foot back from the bottom of the hole others say half inch back for the foot and some say you should use a water pressure sensor to see when you lose water pressure as you move the engine up every hole is different so what you really want to do is take a straightedge and you want the water coming off the bottom of the hull to run just over the water pickups so if you're a three feet from the bottom of the hole then you want the water pickups to be just under the top of your straight edge giving enough space for the water coming off of the hole to rise up and still stay under the cavitation plate the main thing that you don't want is for the water coming from the hole to go over the anti cavitation plate which will suck the back of the boat down and slow the boat way down as well as affecting the right of the boat in a negative way once you have your mounting height correct then we can install the engine putting 3m 42-hundred on the engine bracket around the bolt holes make sure your bolts are ready to push through the transom once the engine is in place it's also a nice trick to put a power pack on the engine so that we can trim the engine once we get close to the transom so that the bracket and the transom are on the same angle this lets the bolts go in nicely and smoothly no hammering or messing up the threads with the bolts through we can put the nuts on and tighten them down you want them to be torqued down to at least 55 foot-pounds I like to put the engines on starting with the port engine so that we can install the engine and completely rig it since the rigging is on the starboard side of the engine this saves us a ton of time and frustration being able to stand there and rig up the engine [Music] we'll go ahead and hook up the steering cylinders to and it's important to check on these fittings to ensure that this little o-ring is inside the fitting before we put the steering hoses on once we have all three engines installed and rigged we can add and configure the tie bar the tie bar setup is pretty simple we want to have the engines towed in just a little so that the boat will track straight as it moves forward through the water we get our measurements to configure the tie bar by installing the tie bar brackets and one side of the tie bar then we can measure the distance between the middle of each bracket we do the same between the prop shafts we are looking to set up the tie bar to be about 1/4 to 1/2 inch of farther apart than the prop shafts so if the prop shafts are 26 inches apart we want the tie bar to be about 26 and a quarter inches apart this will tow the engines in just a little bit allowing the weight coming from each engine to cross each other between 25 to 50 feet behind the boat this is the optimal position and set up to get the boat to track straightly through the water now with the tie bar setup we just check and top off the engine oil the gear lube and install the propellers which means we are ready to configure the system and then top off the steering system put the boat in the water for a test drive and close out our day here for this week's technicians Tuesday we hope you've enjoyed this quick video about how to properly mount an
