    Retune time MEFI Burn, AFR

    A few years ago, my 502 MPI, MEFI-1, VST, 415HP and went to a 509 MPI, MEFI-3, cool fuel, 530HP. Since then I've increased oil supply lines, oil cooler, installed oil temp and water pressure gauges. Motor oil pressure has increased along with flow (AN-6 to AN-10 lines), yet the oil temp has...

    Wiring a 3-wire killswitch

    As I see it, in short, your breaking the 12V after the gauges instead of before the gauges. So the kill switch will remove 12V to the motor but not the gauges. This is the only thing I don't understand. If the purple connects between the NO and COM there will be no 12V to the motor. It...

    Oil seal leaking - questions regarding 864245T yoke

    That is a lot of slop, your able to tilt the race, it should stay in place and only feel a slight drag. The manual link above in previous post and in the bottom of this one has great info to build the drive http://162.144.28.33/lib/mercruiser/manuals/mercruiser39.html#/282

    Wiring a 3-wire killswitch

    I'm assuming your working on a Mercruiser and not an Outboard The kill switch breaks the connection of the purple wire. The purple wire powers everything, and the switch just breaks this connecction. The pic below shows how to bypass the kill switch

    Bunk brackets to angle iron cross member

    If welding is out of the pic, Maybe find some square tubing of similar size, then cut a piece a bit larger then needed to clamp U bolts. This way you could use traditional hardware.

    Pre alpha MC1 - lower exhaust holes?

    I'm finding that pipe and its just installed leaving the lower holes open, but have your same concern. Looked thru the engine manual and drive manual and they both show the same thing. The V8 and other inline 4 and 6 cylinder also show others which cover the holes. Wonder if the first years had...

    Bravo Three Drive (SN:0W958159) Shaft Bearing Assembly

    Looked up your serial number (I should have done that first) and you/we need manual 39. In manual on page 3B-14 it does show a shim (item 42) which would be used for pinion depth http://162.144.28.33/lib/mercruiser/manuals/mercruiser39.html#/204 Preload with new bearings is 6-10 in-lb, old...

    No power at fuel pump

    It appears from the look of the back of the plastic has gotten hot, probably from the relay. If you can jump between the two points without the relay installed, and the fuel pump fuse installed, and it does not blow the fuse then the relay is the problem

    Stringer replacement

    Haven't had much luck with an idea book myself. I select the paper clip in the upper right hand corner. This then opens to buttons in the bottom of the reply screen for uploading attachments (pics). The other method is select the pic icon and then past the location. Maybe copy the pic in the...

    5.7 - Sea water pump replacement - Rookie mistake :(

    BT has you covered, but can also look on the back of the housing, Most all motors are now Left Hand Rotation and only if you have a very old boat will you run into a RH motor.

    tilt/trim problem

    This tells me the trim limit is not adjusted correctly or not working. The Blue/White wire connects to the Red/White wire for UP. For it not working, I would say you may need another trim switch, or the connections to the switch are not making connection

    Mercruiser 3.0 TKS Studder coming off plane

    There is a procedure to adjust idle but it is done in gear and adjusted to 650-700 rpm. The 900 does seam a bit high in neutral so may need adjusting, or timing needs to be checked. Would guess timing should be set 2 ATDC being a 2009, but would need your serial number to verify (0L43100 and...

    No power at fuel pump

    Need a voltmeter to see were power is and what level. When you lump the fuel pump are you going straight to the battery power? If so check the fuse Here is a C-D model (V8 but V6 would be same) but unsure which is a 2000
