    Alpha One Gen 1 Shifter Operation and Cable Movement

    Yes You can relocate the cable end for the controller in a different hole location. Based on the video there are a few options Try for one that allows for 3" of travel. You may then need to make further adjustments at the shift plate assy on the engine

    Need some help just bought 96 chris craft

    Based on OP pics/comments it seems to me the boat in question is more of a "let's just make it work" vessel than a legit, sound, factory spec vessel. Just my opinion, tho IME if I see something suspect on a boat/marine engine it often times is something not correct, i.e. unsafe. AFAIK Volvo...

    4.3 efi tbi throttle question

    52-55 mph in a 21.5 ft boat powered by a 4.3 V6 seems a bit high to me. My experience with Grady White boats is they are built a bit on the heavy side with design geared more for stability and offshore capability rather than speed performance Your investigation has yet to yield any issues with...

    Bravo 3 engine installation / alignment

    The design of the rear mounts changed about ten years ago and the pdf bulletin fun times posted does a thorough job of explaining installation and adjustment. The bulletin does, however "over explain" as they do at times because it covers most/all engine options from mercruiser The...

    Volvo penta 5.0gxi 3869255

    Good info post #7, dodge Would add that crank pos sensor also provides engine rpm data to the ecm. If possible on data items verify rpm number/signal is correct. A visual inspection of sensor/ecm harness connections and an ohms test between sensor connection and the ecm/ground will tell you if...

    Alpha Gen 1 Gimbal Transom Plate Swap

    Pic post #3 shows the mc-1 gimbal housing. NLA new and no aftermarket products ever made (afaik) Your only option is to purchase used oem. Any vintage mc-1 will work but you may have limitations regarding the trim system. There were some changes over the years regarding the trim pump and hose...

    Volvo penta 5.0gxi 3869255

    The 5 volt reference is in regard to the voltage provided by the ecm to various sensors on the engine that provide data for the ecm to monitor engine health. Coolant temp, oil press, map, tps, iac, etc... Most likely you have an issue with one of the sensors, an issue with the harness wiring...

    Upper gearcase pinion bearing replacement

    Pic isn't greatest but only thing I see is maybe one tooth on the driven gear being a bit chewed, can't really tell though General rule is if you replace one gear you replace both, same with bearings. You might find the cost of oem gear/bearing set outweighs the cost of an aftermarket drive...

    Oil Pressure Sensor Or Switch?

    Based on the pics im guessing OP has a carbureted engine, not efi. Pics posted #1 show the oil pressure sender (for the guage) and oil pressure switch (for the fuel pump) Neither of the components pictured in post #1 have any correlation to the audio warning system. OEM for a carbureted...

    Remove drive shaft lower bearing cup

    A standard two jaw puller ought to work for removing the bearing cup. You may need to grind material off the jaws for clearance to gain a tight fit under the cup For assembly/shimming the process is: - Set driven gear/driveshaft/top cap bearing preload (6-10 lb/in for new bearings, 3.5-7 lb/in...

    Merc Smart Craft // 150 Four Stroke - Question

    My WAG is the vessel needs to be properly re/configured using G3 which is only available through a mercury dealer. VV mobile is a fairly limited system but if the vessel is configured port/stbd correctly with G3 along with proper hardware installation your device ought to display the...

    200 verado won’t run above 4500 RPM

    Like dodge stated you should be using a diagnostic tool like mercury g3 to observe live data and confirm both the engine and remote show 100% throttle along with other sensors responding accordingly It's possible by disconnecting the dts remote, ccm, junction box and terminal resistor(s) the...

    Why I do not have new boats.

    Perhaps I'm missing something here but I fail to see a correlation between boat/motor vintage and operator error In regard to the "beeping" from the motor this is an indication of a fault and the audio warning system is allowing the operator to understand something is amiss. Seems to me the...

    Need new plug

    There were a few years in the early/mid 90's during the OMC crossover years that volvo did use the rubber cap plug with a hose clamp over the cast barb on the end of the manifold Remove the clamp and rubber cap and you'll see the cast barb end. Local hardware store will hopefully have a...

    Another gear oil thread... 80w-90 vs. 90

    This calculation is incorrect 1.32 x 128 = 168.96 fl Oz $36 ÷ 168.96 = $0.213 per fl Oz Your math equates to: $4.69 x 168.69 = $792.42 for 5 litres (1.32 us gal)
