    17 vs 19 vs 21 Pitch?

    Trimming it out is a very simple process. Raise the outdrive just until she starts to porpoise then lower it back down just a touch. That's as trimmed out as she gets but flat out you'd be surprised how well it rides on the water. That old straight six is a torque monster. The hydrofoil (whale...

    17 vs 19 vs 21 Pitch?

    Thanks for all the feedback! I've been thinking a 15"x19 pitch might be the way to go. I don't recall the manufacturer of my prop but I buy exclusively from Precision Propeller here in Spokane, WA. Very, very knowledgeable people in there with a 30 day guarantee. If the prop you buy doesn't...

    17 vs 19 vs 21 Pitch?

    I have an old, heavy 17' Apollo cathedral hull. She has the good ol' Mercruiser 165 (GM 250 cu in/4.1 liter) straight six. Currently she has a 15"x17 pitch prop on her. With just me in the boat, on perfect water and at WOT she's dead nuts on 4500 rpm and 40-41 mph. For an old, heavy boat that's...

    Filet Table Engine Cover

    Hi all, Now that I've finally got through the restoration process of all of the mechanicals I've moved onto interior work in my 1976 Apollo tri/cathedral hull. Got the bow seats completely rebuilt last spring and I couldn't be happier with how they turned out for just a couple knuckle heads. My...

    Tri-Hull pros & Con

    I'm a few late to the party but I'll toss in my two cents. I have a 17.5' 1976 Apollo Tri Star I/O. Technically it's a cathedral hull as the sponsons sit higher than the center hull. I've been on actual tri hulls where all three points of contact with the water are even with each other. The...

    Engine swap question - Merc 3.7 vs. 4.1

    This is a real grey area for me. My 1976 Apollo 17' tri hull has the 4.1L L6 and it's proven to be a fantastic marine engine. For being 48 years old on almost all original equipment, it has served us well. But my folks had a 1987 Bluewater 17' I grew up with on the water every summer had the...

    Carb Spacer

    Well y'all, two brand new carbs failed. The first one leaked like a sieve and the second one would not let the engine get under 2500 rpm without suffocating and dying. No matter what adjustment I did to he mixture screws it just wasn't having it. So I took the original carb to my boat guy. Parts...

    Safe RPM range for 165HP inline six?

    I have a 17' tri hull with the Merc 165 straight six. With a 15"x 17 pitch prop I'm nuts on 4500 rpm and 40 mph at WOT. I could go with a 19 pitch, get a little more speed and lower the WOT rpm but for my application the 17 is perfect. It launches outta the water. If I go to a 19 pitch I'll lose...

    Carb Spacer

    I haven't taken the carb back off hoping a buddy who really knows what he's doing stops by to look at it. That is where it leaked since installed. I have the service manual and installed it by the book. I'm not carb savy so I was hoping just buying a new one, since I'm replacing a lot of other...

    Carb Spacer

    This is what originally came off of the original carb. That's the new base gasket that came with the new carb and the original spacer.

    Carb Spacer

    Just got a new 2 barrel Rochester carb for my 76 Apollo with the Merc 165 L6. I'm blanking if the spacer goes above or below the base gasket. Makes sense to me it would get sandwiched between the base gasket and the carb but I just want to be sure. It's crazy what not installing a spacer or...

    Mercruiser 165 6 Cyl. Good, Bad, Okay?

    What is this manifold water reversing kit you speak of? I bought a 76 Apollo with the Merc 165 straight six last year and am slowly restoring it. It does a little bit of everything from no wake speed putting along fishing to cruising to water sports. I'm looking for every upgrade to make it as...

    Stern Drive to Alpha One?

    Ahoy all! I have a 1976 Apollo with a Mercruiser 165 (4.1L inline six). It has the good old gen 1 Mercruiser "Stern Drive" which has served the boat well for 46 years and God knows how many hours. It's beginning to show its age and I'm considering upgrading the outdrive to an Alpha One next...
