Just got my first "go fast" boat its a 1985 27 excalibur pad 5000
for it hope I got a good deal I think I did, was told its a 502 It clearly has a deamon carb with a dart intake and arp head bolts has a velvet drive and a trs outdrive with a 25p prop It tops out at 65 on the speed on at approx 5200 rpm id like to see 70-75 mph any suggestion ? change prop? heres a few pictures.

great looking boat man,

i saw a 27 excalibur years ago all rotted out looked just like that one and i said to myself thats a great looking boat so i went home got on the computer and searched for excalibur boats, thats the day i got addicted to this hopeless money pit of a sport

Try a 23P Mirage or Mirage plus. should pick up couple hundred rpm. What prop 25P are you running now.

Trust me, u got a hell of a boat, there is one in my area with an inboard doing high 77plus, runs and handle great, we actually have a few of them in my area

Theres a thread about a 27 running almost 90 with a 540 and bravo

A 540 will definatly put it up there

Mine with a trs and a 540 that made 630ish just touched 80 and once but always did 77/78. Then did a bravo and always ran 85. Great boat loved it...
