    Mercruiser 888 Unexpected Prop behavior?

    Exactly. Which is why I'm not faulting the 21 pitch prop.

    Mercruiser 888 Unexpected Prop behavior?

    It varies. Sometimes we have 6 people on board, sometimes as few as 2. Sometimes pulling a tube, sometimes just running around the lake/river for fun. Here is the history of the props used on the boat, to my knowledge: (Original?): Mercruiser 48-74888 15" 21P 3-blade rubber-hubbed aluminum...

    Mercruiser 888 Unexpected Prop behavior?

    The 21 pulled the tube no problem... the biggest issue seen (that has always been the case) is that planing speed is 19-20mph which is also the max rated tube speed. We ended up blowing it a bit since I don't seem to have the magic tough to find the happy spot that keeps it on plane without...

    Mercruiser 888 Unexpected Prop behavior?

    Did some lake testing today in better conditions. Bombed the 21 pitch while tubing (lost two blades but only had one spare). Didn't get to running it at WOT. After swapping blades over lunch break, I ran the 19 at WOT. Max speed 44mph, WOT at 4200RPM. 4 people on board. May try 20 pitch blades...

    Rant: Can't catch a break with weekend weather...

    Good day today and I was able to take advantage of it. Thankfully not all lakes that I have access to are flood control lakes... flood control lakes are sky high right now (Monroe is 12ft+!).

    Best "low effort" towable?

    Finally got the tube out today, Worked great, although I'll look to add a booster ball as rope spray was an issue.

    Inherited boat, how bad is this?

    On the flip side, is it worth $60k used after repairs? Probably not. The judgement point should be what a used "working in good condition" used one goes for. What that value is, I couldn't say and will leave to those who have a lot more knowledge. Also, if one doesn't have $10k to spend/hock...

    18ft Boat Launch with RWD Suburban

    For what it's worth (and to hopefully end this hijacking of a thread), I went ahead and installed the disable switch this evening.

    Rant: Can't catch a break with weekend weather...

    This weekend was a bust... Saturday was rain and storms, Sunday was a repeat of two Sunday's before (and I didn't feel like getting beat up by white caps!). But this weekend (Memorial day) is nothing but rain F-M from what I'm seeing. Just can't catch a break...

    18ft Boat Launch with RWD Suburban

    Not really. The way it's set up the pedal has to hit the switch first then push the brake booster rod. Thus, the switch has to be tripped for any truck braking action to occur.

    18ft Boat Launch with RWD Suburban

    Funny enough the binding complaint came from my best friend. He grew up with the boat (it belonged to his aunt and uncle; the uncle and his dad ran it together since it was bought in 77)... but it also didn't have brakes then. My wife never had an issue. But she also never backed it up. My...

    18ft Boat Launch with RWD Suburban

    Simple. The brakes tend to bind up the trailer when the boat's off said trailer (caused issues, especially when backing in to retrieve the boat) and from experience, they're not needed at ramp lot speeds, so it's easier to turn them off beforehand and turn them back on once I'm leaving the lot...

    18ft Boat Launch with RWD Suburban

    I currently run an RWD 1984 F-150 for towing my 16': Never have had an issue with the truck itself. I am in Indiana (no salt water!) That said, to help my chances, I did make a few mods last spring after a season with the boat: -Swapped from road tires to AT tires -Upgraded the rear end to a...

    Mercruiser 888 Unexpected Prop behavior?

    Nice. This thread comes up in google searches for the subject, so at least this information is out there now (although Gemini still gets it wrong :D ) Also interesting that the 233 uses a rare ratio. And I thought my 1.50 ratio was a needle in a haystack... good thing I don't have that! Sounds...
