300 johnson takes long to plane

[nowife007]

i have a 89 300 gt johnson on a 19 ft ebb tide bass boat i bought 2 weeks ago and it takes about 100 yrds or more to plane with 2 people. i put my son 4yrs old in a tube and it wouldnt plane.. all cylinders have 90-105 psi compression. once on plane it runs ok not great but ok i think it should run faster but... the boat has a hot foot and seens to pull wot .it has a 21 pitch prop with a whale tail on it too.. why wont this high hp motor plane help!
