  2. Hey All, I am having some problem maximizing my horsepower. I run a 20' 1997 Javelin 400TE with a Johnson 225 Venom. I am getting 46-48 mph when from what I've read I should be between mid-60s to low 70s. I have a manual jackplate and have been reading that Javelins need to be set up lower than other boats on the jackplate. Can anybody confirm this? I can't imagine that a wrong jackplate set up would cost me this much mph. Is there something specific in the motor I should be looking at? The motor smokes due to a fouled plug so I am changing them and the wires this weekend. Is there anything else I should or could look at? Thanks in advance, Andrew
