270 FV Performance Numbers

Hello all- Going to be Seatrialing 2004 270 FV on Thursday. 350 mag with B3 drive. What are the target performance numbers I should be looking for? Top Speed (thinking ~35kts.)? Cruise speed and RPM? Max RPMs? Thanks.

    35 kts is 40mph...no way.

    On a lightly loaded day very calm water I've done 33mph max.

    Typical cruise is around 3700 rpm at roughly 25mph.  Max rpm is around 4600rpm for me.

    This is with 2 adults and 1 child with water tank and gas filled.

    If I have more people on the boat the numbers change dramatically.

    I own a 270 with a mag 350 mpi and in my opinion it's way underpowered and doing it again I wouldn't have bought that package.

    It's a great boat otherwise.

    Did you have it surveyed?  Make sure the deck around the front hatch doesn't have moisture or any delamination happening.  It's common on that boat.

    I will have survey after seatrial, if the boat runs well and all the "stuff" works.
  • skennellyskennelly ChicagoMember Posts: 1,999 ✭✭✭✭
    Okay.  Usually the surveyor is onboard during the sea trial.  They should know the numbers to expect and if the boat is operating normally.  Also I recommend bringing 3 or 4 adults with you.  You want to test it as close to how you will use the boat as possible.  2 people onboard won't perform the same way as 4 or 5 people.

    BTW welcome to the forum.

    Is this the year with the swim deck issue of being too low and dragging in the water?

    I think that was pre 2003 models.  Mine is a late 2002 model and platform is raised up.

    I don't think I've seen a picture of a lower one. Whoever decided that made a big mistake 🤦‍♂️

    The platform must be almost fully submerged when trying to get up on plane. 🤷🏻‍♂️

    To be fair.  I have seen other boat brands that when I see them in the harbor I say the platform way too low.

    Welcome to the forum @glenncal1 . Will be watching to see how your trial and survey goes. Will a 270 hit 35 knots? Yes. Should it? No. The sweet spot for cruising seemed to be at about 3400 RPM/22-24 mph. Here is a link to a thread that I posted the first year we had our 270. It has pics showing RPM as well as speed as measured by both GPS and speedometer, as well as some fuel burn info from tracking fill ups. Model year 2000 with 5.7L EFI, not the Mag model, so between 260 to 280 hp depending on which source you consult. The boat did not have the swim platform as shown above. I was able to hit 40.8 mph at between 4400-4600 RPM which is absolute redline for that block. So only did it a few times and for a short duration. That was with full fuel and water but just me on board and absolutely perfect conditions. There is an age old debate amongst 270 owners with the 5.7/350 block regarding power. I found it perfectly adequate even with up to 4 people aboard. With 5 I'd sometimes have to get someone to move forward to get on plane more easily, but reality is that I only had that many people on the boat a handful of times. Was mostly the Admiral and I, sometimes our adult daughter and with judicious use of trim tabs I was always on plane in abought 10 seconds or less.

    Nope. Was a calm day, just enough riffle on the water to help the hull break free. Was sunny and cool, about 60F if I remember correctly. Had it trimmed out perfectly. But the poor thing was just screaming. Not something I'd recommend as a regular thing.

    Don’t forget that’s 40mph in Canadian.

    I would agree with these comments, same from my 270..great boat- after 7 years or so still love it...if I get to see it again!
  • skennellyskennelly ChicagoMember Posts: 1,999 ✭✭✭✭
    @rasbury - why wouldn't you see it again?

    Well the sea trial was today. Boat ran good. All systems worked. Top Speed GPS 36-37 mph and we really didn't have a chance to make a nice long run and play with trim and tabs. Gonna have a mechanical inspection and if it passes buy the boat.
  • rasburyrasbury Sanford, FLMember Posts: 6,953 ✭✭✭✭✭
    Must be propped different than most of ours...what was the rpm? Good luck with the rest of the inspection. It's a great boat I think...
  • J3ffJ3ff Member Posts: 3,344 ✭✭✭✭
    Mine does 25mph at 4000 rpms. She's never been very fast. I should prob go to a 22p prop from a 20.. just too lazy to do it at the moment. 
  • rasburyrasbury Sanford, FLMember Posts: 6,953 ✭✭✭✭✭
    Fast enough for my world..
  • skennellyskennelly ChicagoMember Posts: 1,999 ✭✭✭✭
    That engine must be screaming at 37mph

    I did a full throttle run end of season just to see where I was for performance. I was thinking about going 4 blade next season. Anyway...I was able to hit 40mph @ around 4500. One person/20g fuel/lightly loaded. She can easily hit 35 with wife and I with normal gear during the summer running around 4200. 22P stock props - verified by GPS on chart plotter and Vessel View/phone.

    @stuckmoto with more fuel onboard I had to go to 4600 to get 40. The disbelievers are just jealous because they have "slow" 270's. :D

    So today I was running 4000 RPM at 25mph on the dot. With a 383 stroker this seems like very LAME performance. 

    I'm ordering a set of 22p Hill Marine props tomorrow as the 20p's just make me think there is some potential there. Anyone think I should go 24p??

    at 4200 going 35mph this tells me I am severely under propped.
