    94 chaparral 1930 ss with 4.3 prop help

    Yes 4 blade will generally give up top speed but provide better holeshot, sternlift, and lower planning speeds. if you do loaded water sports like me its the way to go.

    A 4 bbl and intake on the 4.3 should get you close to the 220 hp of the mpi. The 4 bbl 4.3 alfa reman engines merc sells are rated at 225 hp

    94 chaparral 1930 ss with 4.3 prop help

    Thats correct on my boat the carbed 4.3 came with a 1.81 drive, the mpi 4.3 which is 220 hp came with 1.62 drive as did the 5.0/220 hp carb and 5.0 mpi/ 260 hp. the drive ratio diff between a 1.81 and 1.62 is similar to about 2” in prop pitch . I repowered my boat from a 4.3 to a 5.0 with a...

    Hydrofoil/Whale Tail Good or Bad

    I will play the other side of the fence. I had decent results from a whale tail on my 17 ft 3.0 l powered boat. Definitely improved holeshot and stern lift and only cost like $35-40 (plastic two piece) back in the day. Did cost some top end Mph. i suspect your boat like mine may have been...

    Dealing with insurance,boat totaled?

    I would think your insurance agent should advise you how to handle the situation with other guys insurance and what policy details you have I have an agreed value in my policy yours may be different. Most importantly I would educate yourself on a current fair value of your boat given market...

    Elbow and exhaust manifold inspection what do you think?

    I don't know which is correct but converted to ft lbs it is 25 &31 ft lbs respectively which is not much difference- either will work, but if I didn't have a torque wrench I'd use a calibrated elbow ...

    Minor shudders at idle

    Agreed they are not the smoothest engines for sure, but yours could probably be improved. Chris gives excellent guidance here. Would be interested to see if you have a loose rocker arm Are ignition components in good order ? what do spark plugs look like ? In the end what the 3.0 l lacks in...

I just did mine and there is some detail in the manual that was helpful- I glued it to the transom and let it fully set up overnight. Then used expander tool - but...

    Engine Replacement Compatibility

    a 4.3 to V8 is pretty easy swap - one the exhaust manifolds are different and down turn elbows after the riser/elbow on top of the exhaust. Both 4.3 and V8 share the same wye pipe so pretty easy drop in. I kept my wiring harness from the 4.3 just swapped ignition modules as the 4.3 doesn't get...

    Engine Replacement Compatibility

    Biggest things to consider are space in engine bay as that would be a lot of work to move rear seats make a new cowling etc . Anything can be modified but then your working on the boat not using it. So if you are purchasing a boat make sure it can fit your long term needs somewhat easily. In...
