    Broken MC-1 Gimbal Housing Repair

    Got a pretty badly broken gimbal housing. In the past I have just replaced the entire transom?but I was wondering what you all thought about the repair kit. I believe the part# is: 18-8311 I've never done one this way, seems like a decent enough alternative. Thanks.

    Converting to electric fuel pump

    Hi…Just did a block replacement on a 4.3, about a 1990. Does not have the counter balance shaft. The original cracked block had a mechanical fuel pump, the new block doesn't have the hole milled for one so I have to go electric. Obviously it is carb and there is no oil pressure switch to run...

    Hey Guys, Alpha One Gen II leaking out of a hole just about the shift shaft coupler. The drive was leaking previously from the weep hole on the lower unit, did an impeller service and replaced the quad seal...now it's leaking out of the upper unit by the shift shaft.

    Shift Interrupter Switch/Shift Cable Replacement

    I occasionally have this come up where I have replaced a lower shift cable, test it (on the muffs), then later get reports that the boat is dying in the water once under a load coming in or out of forw/rev. I understand why it's dying on the water under load and not while on the trailer, but...

    ECM diagnostic...throttle body issue

    Serial #0F452212 5.7L EFI Bravo Three I'm getting no repsonse from the atomizers at the throttle body. To the red wire I get 12v with key on, but no pulse ground to either side (blue or green). I toned out the pin on J2 of the ECM for the pulse ground and with J2 disconnected, manually...

    4.3L Roller rocker conversion issue

    Putting back together 4.3L Vortec 0L082849 and having an issue with valves remaining open. I'm torquing the rockers down to 16lbs as per the manual. This block did not originally have these heads...the heads are off a 2001 block. Seemingly, the push rods are too long as I am using the originals...

    6.2L 383ci hammerhead longblock

    I need to find a build-able block to replace an 07' 6.2L 383ci hammerhead. I'd prefer to build it myself vs just buy one built but I'm not as familiar with the different variations of this block...I'm in the look before I leap stage. Is this 383 considered a "stroker"? I guess I'm not...

    1998 Volvo Penta 8.2L 415-DPX XBYDCE Fresh rebuild, MAP sensor had two broken wires fixed the breaks and replaced the sensor.

    8.2L DPX 502ci Lifter Repair.

    I have this 8.2L 502 that I am swapping the block out on and I just noticed 5 of the hydraulic roller lifters are collapsed (cam, lifters, push-rods, and rockers are all being reused), but I don't recall them being collapsed when I took them out of the engine. No wear to speak of on roller...

    Testing a newer engine on the ground

    Hey guys....I want to build a stand so I can run newer engines on the ground, just wondering if anyone has any design plans they have engineered and wouldn't mind sharing. For later model motors I have a little stand with just an ignition switch, oil gauge, and tach which I connect using...

    Gear oil in outdrive

    Serial tag is missing on the outdrive so I'm not sure which manual to check to verify if this outdrive is really supposed to have gear oil in it, I thought with these older volvos it's all motor oil. Says 275 on the shift linkage plate. Engine serial says CU 61234 and printed on the valve covers...

    Removing engine from a velvet drive

    All the serial tags are missing on both the engine (351) and the Velvet Drive so it's hard for me to give exact details...maybe I'll have to post some pictures. Anyways, all I need to do is pull the motor and replace the rear main seals, but I am wondering if this can be done without removing...

    3.7L 180 Parts and Information

    Hey there. I have a new boat project, it's a 35' Searay with dual Merc 3.7L 180's Serial# B730773. I'm having a hard time finding a few parts locally, but I believe if I am not mistaken that the head, connecting rods, pistons, and flywheel are from the Ford 460. Is this true and does this mean I...
