    Manual jackplate adjustment....

    Yes, I am measuring from the pad to the propshaft. I would like to be able to turn sharper without cavitation, and maintain a plane while traveling at slower speeds (20mph). Thanks for the link, I asked them the question on which way to turn that, (hard to get to) , nut in the middle, to lower...

    Manual jackplate adjustment....

    I have a Pulsare 1850, w/ Merc 175 Optimax, mounted to a 5.5 inch manual jackplate. I would like to LOWER the engine for better all around performance, hence, tubing, skiing and such. I can back off the four side bolts, but after that, I'm lost. There are four nuts, two on top and two on the...

    A funny thing happened.........

    Ok, all kidding aside. I took my boat out yesterday for a test run and once up on a plane it ran perfect. At about 4000rpm, a temp of about 125. Once I dropped off plane, it heats up quick. At about 160 I hear the alarm and have to idle till the temp can recover. Is BLOCK PSI, the water...

    A funny thing happened.........

    to someone I know. Let's say he, has a Mercury Optimax 175, 2004. Now, let's say he, flushed the engine using the plastic plug in the back of the powerhead. The next time he ran the boat, it ran perfectly, at speed, on a plane, but, if he held it just below planing speed, the overheat alarm...

    Cajun Country Checkmates

    Checkin in from Metairie, seconds from Bonnabel boat launch. When the Lake Pontchartrain cooperates, it's a great place to run. I too spend many days at the Beach, with my two kids, 14 and 16. We also make an annual trek to Lake Martin in northern AL. Lake Martin is a little piece of heaven...

    Lake Martin Vacation....

    Thanks for the recommendations JW. We do alot of tubing, wakeboarding and skiing; therefore I must compromise my setup. In your opinion, how much more speed could be gained by raising the engine and running a Tempest Plus? I am already hitting my max revs when totally trimmed out.

    Lake Martin Vacation....

    Chine walk? Yes. At about 52 the hull pops free of the surface tension, noticeably, and you must balance the boat on the small pad, which I guess is all that's left in the water. It takes time behind the wheel and no rogue waves to keep her at top speed for any length of time. Thanks for the...

    Lake Martin Vacation....

    Thought I'd share this photo of my Checkmate Pulsare 1850BR. Been waiting for 2 years to get a shot of her wide open and trimmed out.
