    Water inside the engine compartment

    1. If the water in the bilge is from rain or other source (PLEASE CLARIFY), Do you know how the water entered the boat?? Why didn't the bilge pump work and pump the water out automatically? I would get that fixed first!!!!!! 2. As long as the water did NOT get to the dip stick tube where it...

    4.3L Thunderbolt V Ignition

    Dieter, Manual 18 which shows carbed TB V ignitions clearly shows a second KNOCK control module used for the V6. The next V6 manual is 25 but only speaks to the knock module but has NO images of the ICM or Knock module (Poorly written manual for TB V) This past spring My friend (ONLY...

    4.3L Thunderbolt V Ignition

    If it were me, I would look for any version of the thunderbolt ICM for a V6, IV or V early version. TB IV did not have the mean best timing or the knock sensor and module so some minor wiring changes would need to be made but it WILL work. I believe the early TB V modules also did not have the...

    Shift cable adjustment driving me crazy

    Being the control cable is at its Max limit this is a problem but may not be your major issue. You need to remove drive and review what we discussed. No decision can be made yet.

    Shift cable adjustment driving me crazy

    Measuring the short shift cable slack takes some practice. It is a touchy feely kind of procedure. I bet as it is new it is in spec you just havent been taught exactly how to perform the measurement!. If you want to discuss text me and we can talk about it. Make sure you understand exactly...

    Shifting troubleshoot nightmare

    You really need to start your own thread. Piggy backing on an old thread is not good. The original thread has NOTHING TO DO WITH YOUR ISSUE. Others will read thru it and get confused and possibly give you incorrect advice based on the prior issues contained in the original post/thread. Your...

    Shifting troubleshoot nightmare

    Yes, The bottom shift shaft busing in the bell housing has been known to move up allowing the shift shaft to also move up which will not turn lower unit shift shaft enough for reverse. I have personally found this as a root cause in Gen II's only. Not in Gen 1 You can possibly see a color...

    Spoke with him last night. His drive is an SEI, he said it had the preload pin vertical drive shaft in lower so it appears to be period correct. He seems to have a very good mechanical apptitude and understanding of the basics. I gave him several specific things to look at so he will do so and...

    Alpha one shifting problems

    I have an idea, Maybe start a new thread of your own and include EXACTLY what outdrive you have. R, MR, Alpha Gen 1 or Gen 2. Engine size, type or boat doesnt matter. Only the specifics of the drive. Also, the spool. Was it steel or brass/bronze? Very important!!!!!!!!!!

    Shift cable adjustment driving me crazy

    Here is my written procedure. I have used this for many years. If it fails then the basics of cable install or worn linkage parts are responsible. As mentioned above, When tightening the Brass threaded cable fitting into bell housing from drive side - ONLY 1-2 threads should be visible (~1/16"...

    Shift cable adjustment driving me crazy

    There is NO WAY the cable was 50 years old.....................That said, What was the cable part number you purchased and where did you purchase it? Older designs the cable threaded into bell housing from transom side. ALL newer designs thread into bell housing from drive side. WE NEED TO...

    1971 Larson GM 250 Inline 6 165 HP

    A 143 degree stat will have a 150-160* under normal operation. Today you get 140* stat. I am not sure they still sell a 143*. Also location of sender may show higher or lower a few degrees. every boat I work on with a 140* stat runs at about 150 ish at idle and normal running rpms. After a...

    1971 Larson GM 250 Inline 6 165 HP

    No one said a NEW boat. A mid 1980's and newer would be a better choice and there are tens of thousands of them out there. At least that technology level is still very much in use and parts are readily available. FYI, inline 4 cylinders Mercruisers make 140 HP in newer boats. that inline six...

    1999 Mercruiser 350 Engine Tick - Rebuild or Replace?

    In my opinion, if you do a compression check and it fails, Most likely one or two cylinders have failed, Most likely ring lands have broken and possibly more damage. Lifters and cam are a secondary result of piston/ring failure. Rebuild by a reputable shop will be at least $4500+ If you do...
