    Prop pitch change

    Really depends on which prop you are thinking of getting and what your current Aluminum prop does in terms of WOT rpm (3500 is way low for wot, assume that is cruise speed or tach is off). If you aregetting to the top of reccomended rpm range for engine AND you buy a basic stainless prop like a...

    2009 Sea Ray 185 4.3 TKS - a few questions.

    Not sure what questions you had. Looks good only only comment would be why use a non marine rated ignition module, generally issue with non marine rated electrics in a boat is spark potential in environment where gas vapors can accumulate i found merc thunderbolt v modules on ebay for around $200

    Changing to stainless steel prop

    What are you looking to improve ? Ive found four blades to improve hole shot stern lift and planning speed. Larger boat like that may like a revolution 4 in 15 or 16” pitch . If you aren’t dead set on stainless might be good to try an aluminum four blade like a michigan vortex 16” . They are...

    Prop Recommendation

    Frist make sure the engine is in good shape tune up wise plugs, cap rotor, fuel filter, carb is clean etc, ti tming checked set. I would think a 19" would do pretty well on that rig. Based on your numbers I dont think the suggestion of a 17 mirage is unsound, as that would get your WOT up...

    5.7L Mercruiser; Engine Running Weird

    measure the fuel pressure and see if you have 4-6 psi at the carb. Possible fuel pump is working intermittently but more likely might be the antisiphon valve on fuel tank outlet. Remove and clean, run it without for a while and see if problem goes away

    Edelbrock 1409 tuning

    You can try leaner and see if that makes it worse . Edlebrock makes a kit with 3 different accelerator pump nozzles. That may be what u need . That cured my bog on my 5.0 with a 1409

    Engine alignment

    I think that looks pretty good. I also had one that was difficult to push the bar in , or more difficult than i would like, i think you end up with so much grease in the coupler when you do this several times. I end up putting the drive on and over the last six years /250 hrs have had no issue...

    Waterproof engine compartment?

    What i noticed on the newer sea rays like 195 and 205 sports with a similar hinged sunpad is a aluminum U channel that runs fore to aft under the seam in the sunpad. I never thought of it till u posted this, but you can cut a hole aft and use this as a gutter. You can see it in the engine...

    Question about a 5.0 volvo penta

    I would just go with new manifolds. Agree with penfield on crack or rot through gasket between manifold and head doesnt have water at that spot. Crack is likely due to lack of winterization. If purchasing this boat that has obviously had a hard overheat and isnt 100% fixed i would pay a price...

    2015 vortec 350’s repower issues

    I think on some remanufactuered engines like the mercruiser 357 alpha and bravo engines they machine the block for mechanical fuel pumps. Not sure why they do that or what advantage it is vs electric...
