    MSX 150 Will Not go over 2900 RPMS

    I have a 2004 MSX 150. It has very low hours on it. It seems t orun fine while out of the water however when I place the craft in the water it will not get over 2900 RPM's. I have checked the service manual for everything the limits the RPM's however I have not found anything wrong. Does anyone have any ideas as to what I should look at next?

    Welcome to the Hulk

    Have you checked the mechanical basics?

    Compression on each cylinder?

    Has the oil been overfilled?

    Is there oil in the air intake tract?

    MSX 150 Will Not go over 2900 RPMS

    I have checked everything mechanically> I have been using the service manual as a guide. Everything seems to be right. I have synced the ETB and PPU. Cleaned both fuel injectors. Made sure there are no restrictions on the exhaust system. Cleaned the ETB. Checked the Wastegate solonoid. The Wastegate is not stuck as mine is loose. Compresson is fine. Plugs are fine. Never overfilled the oil. Now I do not know what else to do. Any ideas?

    I have also checked all the RPM limiters as well and the all seem to be working fine.
