    Repowering your boat with Michigan Motorz-gctid380542

    Michigan Motorz

    By: Loren Haus

    As we come into another season of boating, I wanted to say a few things to the members and visitors on BOC to help everyone have a great year.

    First and foremost, I want to thank the customers on this site who have purchased engines from us. We greatly appreciate your business, and we are making changes all the time to continually serve you better!

    We realize, as boaters ourselves, when you go out to use your boat, you want to USE it. No one wants to be tinkering with a carburetor, or figuring out why its overheating, or is blowing oil everywhere while you are trying to get a couple of well-deserved relaxation hours in with your family and friends.

    With that said, I would like to point out a couple of things to remember if you choose to re-power your boat with a long-block (new or re-manufactured) or a partial engine package (such as our bronze, silver, or gold packages) that will keep you on the water longer....

    1.) If you are looking to replace just your long-block and reuse your accessories....

    Before you make the call to order a replacement engine, it is VERY important to determine the exact cause of failure so a replacement engine will not fail the same way the original engine did. When you call to place an order, we need to know what happened so we can make sure you have all the necessary parts so it DOESN'T HAPPEN AGAIN.

    For example: if your engine overheated, make sure to replace the water shutters (flappers) inside the exhaust Y pipe. They are there for a reason-to prevent water injestion into the engine. If a customer calls to order a engine, and does not specify that his engine overheated, we will not be able to recommend purchasing additional parts to correct the CAUSE of the problem....like a new water pump impeller, new thermostat, etc.

    One nightmare is bad enough...better to make time to do it right the first time.

    2.) In the case that your are replacing a long-block for a throttle-body injected or multi-port fuel injected engine....

    Engine ignition systems are very dependent on clean, tight ground connections. This is even more important in the case of fuel injected engines. As a tech, I get more calls on fuel-injected engines not running properly after purchasing a longblock than anything else. I have had customers request sending their complete bobtail engines back to me for diagnostics on my engine runstands.

    In nearly every case, it is ground-wire related. Most sensors on fuel injected engines have 3 wires: a sensor wire which provides information to the ECM by means of voltage change, a 5-volt reference wire, and a GROUND wire. Without a good ground, the sensors will NOT communicate with the ECM properly, because it cannot send the proper voltage signal to the ECM. Because wires are so thin on fuel injected engines, it is VERY important when disassembling your old engine to take care not to tug them out of their sockets. Always make sure you disconnect sensors by grabbing the plug.

    Thermostats are also a huge contributor to a fuel injection engine not running properly. A thermostat that is stuck open will make the engine run cooler than it should, which will make the engine run pretty rough at idle.

    Fuel systems are also a major contributor to TBI and MPI engine trouble. Low fuel pressure from tired and old fuel pumps, fuel lines that got kinked during the removal and installation on the new engine are all common.

    3.) Engine timing is crucial! I cannot over-emphasize PROPER ignition timing. It's such a simple thing to do and check. Failure to time an engine properly will cause catastrophic failure within 10 hours of using a new engine. I STRONGLY recommend to customers to check their ignition base timing AND the total advance yearly during the annual boat tuneup/oil change. This simple 2-minute check can save you THOUSANDS of dollars by identifying early failure of an ignition module or photo eye in thunderbolt distributors.

    4.) Everyone who owns a boat should know by now to do the basics. Water pump impeller, oil & filter change, spark plugs, cap/rotor/plug wires, etc. Maintenance is good, preventative maintenance is best. It never fails....that one thing you "forgot" to do always comes back to bite you in the butt.

    While we do our best to help hundreds of customers weekly, we simply cannot be there to see the original engine(s) and what caused them to malfunction. We DO want everyone to be on the water enjoying their time with family and friends. Please help us by being detailed about what happened so we can help you better!

    From the Michigan Motorz Team: Happy boating 2012!!!!!!!!

    Thanks for the new base engine installed this winter...before I was able to start the break-in my fuel tank failed. :drama.

    My transaction was real smooth, great communication. As to the motor, tell you as soon as the next project is done, might be awhile.

          I also will add my thanks. It is good information.

          A year or so ago I had a problem with my Ford Diesel truck while on the road, Talking to the mechanic about boats, he wanted to sell me one. A Chris Craft.

          He was on his 3rd engine, same problem. Water got in the engine and ruined it. Low running time on the last two.

          He used all the bolt on stuff including the MANIFOLDS AND RISER. He was a mechanic but not a boat mechanic.

          I suggested that likely was his problem.

          Fits with what you are saying and obviously it is a problem.

          Your company is mentioned on this site often. Always good.

          As a boater you might enjoy our community. The brand and type doesn't matter. Its boating that matters.

          Feel free to join us.

            Loren, I'm also glad to see your thread here. Your company has a great reputation, and as you no know, we promote MM when we can.

            I must say though..... we're not seeing any of the "kick-back" money. Is there an issue in your accounting department?

              I'm glad to read where you touched on the exhaust systems and ignition timing above BASE advance (all too often given zero attention). Either may be over-looked, and as you implied, when left as-is these can cause a repeat of the original problem.

              I call this our "forensic work" to determine what the cause was.

              Regarding Ignition timing... do you offer engines equipped with fully engraved harmonic balancers? I wish that all came engraved as I'm a old school strobe light guy!

              Keep building them, Loren........ and we'll try to keep consuming them!

                Rick, I thought their kick backs were the reason BOC ran ad free unlike other Forums.

                    You know, now that you mention it....im not getting "kick-back" money for selling tons of MerCruiser complete drop-in engines and drives....and I promote them every day! LOL :greedy_dollars:

                      Loren,

                      Do you supply the Horsepower, Torque, and Brake Specific Fuel Consumption curves with your turn key engines?

                        All of the complete turn-key engines have the at least the horsepower listed on the site. Torque is listed for most of the MerCruiser plus-series engines (the engines with the flame covers). If you go to http://"http://www.mercurymarine.com...eries-engines/ you can click on the engine you are interested to find specific fuel consumption data and the data for the boat used to perform the engine tests.

                          What is recommended for first splash / break in procedures first run on the water after the engine swap? How soon to change the oil ect...

                            That doesn't really answer my question. Do you supply the complete curves for the complete RPM range of the engine? Specifically, Horsepower vs RPM, Torque vs RPM and BSFC vs RPM.

                              If you click on an engine you want information on, then click "view engine test", you will find a page like this: http://"http://www.mercurymarine.com...-alpha-4v-bhb/
