I was on an ILS 16R; planning to do a touch and go and then return around for another approach; and was cleared for the option roughly when I reported in to the Tower. PAE Tower then issued 'Boeing XYZ heavy; you are clear for the taxi test on 16R.' I received a new clearance; 'Break off your approach and begin a right turn; 250; prior to the threshold of 16R.' I could visually see a large Boeing jet taxi enter the runway. He waited for a short period of time. Paine Tower then said 'Boeing XYZ heavy please start your taxi test.' The Boeing jet only taxied a short distance down the runway; and then turned off to the left on one of the first taxiways (it was not a full length high speed taxi test).I received a new clearance; 'Disregard earlier instructions; you are cleared for the option' ...with no other qualifiers or warnings. I landed roughly at the 1;000 foot stripes and rolled down the runway without braking; while reconfiguring the plane for a takeoff (go around activated; flaps up; cowl flaps open; set trim; etc.) and then accelerated into the takeoff roll. Immediately after takeoff I was blown and buffeted significantly from left to right and had a temporary loss of control. I recovered and re-established the climbout. It seems that the large Boeing aircraft; *perpendicular* to the runway and just off the left side; was perhaps doing an engine runup test with his engines aimed at the runway; or was aggressively using power to get the plane moving ... in any event; it is clear that I was a victim of jet blast moving across the runway from a large jet.I called the Tower Controller after my last lap and discussed this with him. He indicated that the Boeing pilots are generally asked to use minimal power on taxi for this very reason. My point in filing this report is to raise visibility: while we all read and think about wingtip vortices; and get warnings from the Tower about this; I have never in decades of flying read about or thought about the risk that I encountered. If the runway is clear; no vortices; no warning from the Tower; etc. Then I assess my landing risk level as normal. I have never thought to look around at all of the surrounding taxiways; up and down the runway; on parallel taxiways where a plane may be turning; etc.; to try and anticipate which large jets might be jet blasting across the runway as they maneuver. Should I have made those checks? Presumably. Should the Tower be issuing 'jet blast' warning; possibly? Should Ground Control not grant taxi permission to the jet if there is a plane landing behind? That would be nice; but perhaps hard to coordinate between Tower and Ground positions. Anyway; scared me; both because of the loss of control/recovery and because I realize I have never thought to guard against this issue.
A single engine pilot performing touch and go landings at PAE lost control during takeoff after a Boeing heavy jet exited Runway 16R and parked perpendicular to the runway with power apparently above idle.
